TEST: Solar Guitars V26FBB Baritone

When it comes to electric guitars that symbolize the metal genre, few shapes are as iconic as the Flying V. The sharp edges and design optimized for standing play are as closely associated with the heaviest music genres as any guitar shape can be. Over the decades, additional models have joined the originally 1958 Gibson-developed instruments, aimed at dance musicians (!), enhancing the aggressive look of these models and making the original’s comparatively soft curves seem quite moderate. The Scandinavian company Solar Guitars, which manufactures most of its instruments in Indonesia, offers such a model with the Solar Guitars V2.6FBB Baritone, and we have the baritone version for testing, which features several interesting and unusual details due to its construction.

#### The Construction of the Solar Guitars V2.6FBB Baritone

First, a few basic details for the baritone guitar novice. A baritone guitar is primarily defined by its scale length, typically ranging from the long scale of 648 mm to around 760 mm, similar to a short-scale bass. Baritone guitars can also be constructed with a short-scale bass length, as seen in my custom model from Framus.

[My Favorite Guitar - Framus Panthera Baritone Axel Ritt Custom](https://www.amazona.de/feature-my-favorite-guitar-framus-panthera-baritone-axel-ritt-custom/)

The longer the scale, the tighter the tone due to higher string tension, but playability decreases with longer scales. Each player must decide their preferences. The Solar Guitars V2.6FBB Baritone features a scale length of 673 mm, just 3 cm longer than the standard Fender scale. The main advantage is the marginally increased spacing between frets compared to a long scale, but this moderate baritone scale length should be compensated with an appropriate string set.

#### Why Compensate?

The purpose of a baritone guitar is to allow for a lower tuning than the standard tuning of an electric guitar. Since downtuning has become common in the electric guitar realm, it is no longer a novelty. However, as many downtuners know, one must use the thickest strings available on a regular guitar scale to avoid a flabby tone. This is mitigated by the longer scale of a baritone guitar. The longer the scale, the thinner the strings can be, and the tighter the attack due to higher string tension. Additionally, strings must have a minimum length, as seen in this case where the lowest string, due to the reversed headstock, extends about 15 cm to the nut, then the entire scale length, and finally through the body via the fixed bridge for better sustain, totaling roughly 95 cm plus one or two windings at the tuner.

To compensate for this feature, Solar Guitars uses a string set with a wound G string, clearly favoring chord and riff play. The string with the thinnest winding also has the thinnest core, making it less suitable for bending. For example, the 3rd string (G string in standard tuning) must be bent nearly twice as far as the 2nd string (B string) to achieve a similar pitch change. To address this, I would use a specialized baritone set, like my Pyramid Signature set, which includes the thickest, still cleanly vibrating plain string to compensate for this issue.

#### The Wood Selection

Upon first handling the Solar Guitars V2.6FBB Baritone, the incredibly light weight of just 2.7 kg (!) is immediately noticeable, despite the instrument having mahogany body wings, a neck-through maple neck, and an ebony fretboard. Clearly, very lightweight woods were selected, which does not negatively impact the instrument’s weight despite its large dimensions. Due to the very light weight and the extensive neck, the instrument is slightly top-heavy, but not enough to impact playing comfort. The body is shaped on the upper and lower sides to enhance playing comfort. The appearance also gains a touch of elegance, although the applied flamed maple veneer is only subtly noticeable. The C-shaped neck is very comfortable to play and, with a nut width of 43 mm, has relatively small dimensions, benefiting playing comfort. The synthetic bone nut made from PPS is suitable for all players who prefer non-animal products on their instruments. The fretboard has 24 frets, meaning the neck pickup has to be placed slightly further back, moving away from my personal favorite position under the 24th fret. This is a matter of personal taste, not a critique.

The instrument also features the Solar Guitars logo at the 12th fret with no fretboard markers on the front view, only side dots along the fretboard edge.

#### The Hardware of the Solar Guitars V2.6FBB Baritone

In line with the instrument’s all-black design, all hardware is entirely black: bridge, tuners, master volume knob, master tone knob, and the three-way switch all share a matte black finish. Unfortunately, Solar Guitars chose an unfavorable spacing between the tuner posts. The tuners are too close together, making it a fiddly task to turn the tuners cleanly and evenly when they are parallel to each other along the headstock, affecting tuning comfort.

Solar Guitars opted to place the jack on the back of the body. This has pros and cons. The advantage is a cleaner, more uniform look when viewed from the front. The disadvantage is that the guitar or cable may rub against the thigh depending on how the instrument is held, causing uncomfortable pressure. Additionally, the cable must be looped extensively if secured and anchored at the strap pin, as is commonly done.

#### The Pickups

The Solar Guitars V2.6FBB Baritone is equipped with two Seymour Duncan humbuckers labeled "Duncan Solar," which can be split via the push/pull function of the tone knob and are allegedly made in Korea. Unfortunately, I could not find additional information on the pickup specs beforehand and will rely solely on my hearing for the sound files.

#### The Solar Guitars V2.6FBB Baritone in Practice

When you first pick up the Solar Guitars V2.6FBB Baritone, the very light weight is immediately noticeable in a positive way, especially since this light weight does not negatively affect the vibration behavior or sustain, as is the case with many other instruments. The relatively short scale for a baritone guitar is easy to handle, especially since the instrument is well set up from the factory and required no adjustments.

Of course, this Flying V version remains practically unplayable while sitting, unless you place the lower horn of the body between your legs and assume the typical classical guitar holding position, which is far from an official heavy pose. However, the instrument is easy to play while standing, especially if you prefer rhythm playing. The instrument handles well and, due to the wound third string, is primarily suited for rhythm playing, as noted by references such as Malcolm Young of AC/DC, who played with a wound G string his entire life.

#### Regarding the Pickups

My opinion on the pickups is somewhat ambivalent. Interestingly, the single-coil setting is of significantly higher quality than I am used to from other pickups of this type. However, I find the humbucker setting to be somewhat lacking in transparency.

The relatively low output level for a metal guitar has the advantage of allowing greater tonal variety when using additional distortion or overdrive pedals without the amplifier being overwhelmed by the high output of the pickup. The extent to which one finds the right or optimal combination, as always, largely depends on personal taste. Personally, I would have preferred a bit more character in the pickups, especially given my higher expectations from a manufacturer like Seymour Duncan.

All in all, one must keep in mind the relatively low price of the guitar and that it offers a very good workhorse tailored to the right target audience.

### Conclusion

With the Solar Guitars V2.6FBB Baritone, the Scandinavian manufacturer has an instrument in its portfolio uncompromisingly built for the heavy genre. With excellent craftsmanship and good sound, the instrument offers a baritone alternative for the budget-conscious to moderate spender, still performing well even in an F# tuning.

The 673 mm (26.5 inches) scale length of the Solar Guitars V2.6FBB Baritone enhances its playability and tonal performance. This extended scale length is particularly beneficial for lower tunings, providing tighter string tension that helps maintain intonation and sustain. Guitarists who frequently play in drop tunings or need a guitar that can handle a wide range of tunings will find this feature especially useful.

#### Neck Construction and Profile

The neck profile, while described as a C-shape by the manufacturer, leans more towards a D-shape, offering a thicker, more substantial feel that many players prefer for stability and comfort. The neck-through construction further enhances sustain and resonance, as the continuous wood piece allows vibrations to travel more freely through the instrument.

#### Pickups and Electronics

The Fishman Fluence pickups installed in the T1.7AD are renowned for their innovative design and tonal versatility. Unlike traditional pickups that use wire windings to generate sound, Fluence pickups use a printed circuit board to create consistent, noise-free tones. This technology provides the T1.7AD with two distinct voicings, accessible via the push-pull tone pot:

1. **Modern Voicing**: This setting delivers a high-output, aggressive tone suitable for metal and hard rock, with tight lows, pronounced mids, and crisp highs.
2. **Vintage Voicing**: This setting offers a more classic, PAF-like sound, with warmer, rounder tones ideal for blues, jazz, and classic rock.

 ### The Evolution and Impact of Seven-String Guitars

Over the past few decades, the design and use of seven-string guitars have undergone significant transformations, shifting from niche to mainstream and back to a specialized tool for modern guitarists. In the late 1980s, Steve Vai brought the seven-string guitar into the spotlight with his JEM Universe model, featuring an additional low B string. Initially, Vai wanted an additional high A string, but it kept breaking, leading to the revolutionary low B string. This innovation captivated the guitar community, particularly with the rise of Nu-Metal bands like Korn, who tuned their guitars down to A, creating a new stylistic element that became integral to the genre.

In contemporary music, downtuning remains extremely popular. However, most musicians achieve this with standard six-string guitars or, in specialized cases, with baritone guitars or even eight-string guitars in the extreme Djent genre. Despite the changing trends, the seven-string guitar remains relevant, as evidenced by the Solar Guitars T1.7AD Aged Natural, a modern instrument designed to meet the demands of today’s guitarists.

### The Construction of the Solar Guitars T1.7AD Aged Natural

Understanding the construction of the Solar Guitars T1.7AD Aged Natural requires a deep dive into its design and components. What sets a seven-string guitar apart? Primarily, the additional low B string allows for powerful, bass-heavy riffs, especially in high-gain settings. However, the true advantage lies in the extended tonal range. For example, baritone guitars, with their longer 760 mm scale length, provide a tight, bass-heavy sound but struggle to achieve high notes. Conversely, eight-string guitars often have such wide fretboards that techniques like bending and vibrato become challenging. A seven-string guitar strikes a balance, offering the full range of a standard guitar plus an extended lower range.

Solar Guitars addresses the common issue of the low B string feeling "floppy" by extending the scale length to 673 mm, increasing string tension and reducing slack. The initial impression of the Solar Guitars T1.7AD Aged Natural is somewhat reminiscent of a Telecaster, though the resemblance is superficial. The body shape, wood selection, and overall appearance diverge significantly from the traditional Telecaster.

#### Body and Wood

The body of the T1.7AD is made from alder, chosen for its balanced tone and lightweight properties. The finish is intentionally "aged" to avoid a high-gloss look, instead opting for a matte sheen that gives the guitar a used but well-maintained appearance. This finish is far from the heavily relic-ed look seen on some guitars but provides a subtle vintage aesthetic.

#### Neck and Fretboard

The neck is constructed from maple and glued into the body, ensuring stability and sustain. The fretboard is made of ebony, a dense wood known for its smooth feel and durability. It features 24 jumbo stainless steel frets, which offer longevity and a comfortable playing experience. To aid navigation in low-light conditions, the fretboard includes glow-in-the-dark side markers, which are effective even in dim environments.

While the neck is advertised as having a C-shaped profile, it feels closer to a D-shape, providing a substantial but comfortable grip. The absence of binding on both the neck and body gives the guitar a sleek, modern look. The strap buttons are visually cohesive with the guitar's design, but upgrading to locking strap buttons is recommended for added security.

#### Hardware and Electronics

The hardware of the T1.7AD is uniformly treated with a patina finish, giving the tuners, headstock, scratch plate, and Evertune bridge a cohesive, worn-in appearance. The Evertune bridge, known for its complex spring system, maintains consistent string tension, effectively keeping the guitar in tune despite changes in temperature, humidity, or playing pressure.

The Evertune system offers two main settings. The first allows for normal vibrato and bending techniques, while the second setting compensates for excessive string pressure, preventing over-bending. This compensation feature is beneficial for rhythm playing but can feel less expressive for lead techniques due to the system's modulation restrictions. Interestingly, the test model arrived with only the low B string set to compensation mode, while the other six strings were in standard mode. Whether this was intentional or an oversight, the flexibility to adjust each string’s settings to personal preference is a significant advantage.

Upon inspecting the body, it's evident that nearly half of it is hollowed out to accommodate the Evertune bridge and electronics. This modern version of the Evertune bridge requires less body routing than earlier models, reducing weight and preserving more of the guitar's natural resonance. Despite this, the T1.7AD’s body thickness of approximately 4.3 cm and weight of around 4.2 kg is heavier than most guitars, contributing to its solid feel and substantial presence.

The T1.7AD features Fishman Fluence pickups, renowned for their versatility and clarity. These pickups are controlled by a master volume and tone knob, with the tone knob functioning as a push-pull switch to toggle between modern and vintage voicings.

The Evertune bridge continues to evoke mixed feelings. On one hand, the ability to take the guitar out of its case and play without tuning adjustments is a significant convenience. On the other hand, the slight delay in response when performing bends can feel unusual, as the system needs to detect and react to the bending motion before it translates into pitch change. While this can be adapted to with practice, traditional players might find the required finger movement more extensive than expected.

However, the sustain behavior of the Evertune bridge has markedly improved. Early models were known to dampen sustain, but the current iteration allows for long, resonant notes. Despite the significant body hollowing, the guitar’s resonance and sustain are excellent, highlighting the effectiveness of the design improvements.

The T1.7AD excels in high-gain environments, delivering powerful, articulate tones. Surprisingly, it also performs well in lower gain settings, demonstrating versatility. The Telecaster-inspired body shape offers a refreshing departure from the common Super Strat designs prevalent among other manufacturers. The playability is excellent, despite the large neck and fretboard dimensions, with a well-designed neck joint facilitating comfortable access to the upper frets.

One minor drawback is the "spring ring" effect associated with the Evertune bridge, similar to the noise from unmuted springs in traditional tremolo systems. This can slightly muddy the sound during palm-muted playing, although it is a minor issue compared to the overall benefits of the system.

### Conclusion

The Solar Guitars T1.7AD Aged Natural is a noteworthy addition to the company’s lineup, catering to guitarists who seek a blend of modern functionality and classic aesthetics.

If there were a prize for the least glamorous product in the music industry, it’s a safe bet that a DI (Direct Injection) box would win almost every time. Typically, these boxes are tucked away in a corner of the stage, their presence unnoticed until something goes wrong—like generating unwanted noise.

### The Concept of a DI Box

For those unfamiliar, a DI box is a device that converts a high-impedance, unbalanced signal into a low-impedance, balanced signal. This transformation is crucial, especially when connecting a passive electric bass or an electric guitar directly to a mixing console, bypassing the traditional amp and microphone setup. Unbalanced signals tend to degrade after about 20 feet (6 meters), especially with passive pickups, leading to significant signal loss. Active pickups can extend this range to about 65 feet (20 meters), but this is mostly within the realm of EMG, Fishman, or similar pickups.

Electric guitars also benefit from DI boxes when not using standard amplifiers and speakers. In scenarios where the signal is processed digitally, an unbalanced signal can cause issues. Balanced signals are less susceptible to noise and interference, ensuring a cleaner sound over longer distances.

### Practical Applications

A DI box is indispensable in a wet-dry setup. This configuration splits the guitar signal, sending one path to an amplifier and speaker for traditional mic pickup, while the other path, through the DI box, goes to effects processors. The resulting processed signal can then be reintegrated into the overall sound system, either through a speaker or directly into the PA system, depending on the desired effect.

TEST: Solar Guitars A1.7C G2

 Sometimes you are proven wrong. Who hasn't asked themselves how many professional providers the guitar market still has room for? You would think that the commercial sector has long been covered, but every now and then you are surprised. For example, the company Solar Guitars, founded in 2017, managed to build up a steadily growing community of users through the now mainstream presence of extreme metal genres and the constant promotion by the Swedish owner and YouTuber Ola Englund, without it being possible to recognize a unique selling point at first glance. The test of the Solar Guitars A1.7C G2 should show to what extent there are some special features in the construction of the brand.

The construction of the Solar Guitars A1.7C G2

If you look at the artist page on the Solar Guitars website, the manufacturer's target group is clearly defined. From melodic power metal to grunting burp metal, everything that can be found under the style "metal" is combined. It is all the more surprising that the preferred body shape, in addition to the obligatory Explorer and Flying V shape, is reflected in the classic Powerstrat in the style of the Ibanez RG series. Perhaps portability also plays a role; anyone who has ever tried to transport something B.C. Rich-like without a suitable shaped case knows what I'm talking about.

The Solar Guitars A1.7C G2 presented for testing is visually comparatively understated, although the matte black finish in combination with 2 explicitly designed shapings in the cutaway area gives off a hint of sci-fi attitude. A quick look at the graphite nut width of 48 mm and the number of Solar Locking 18:1 tuners - this instrument is a 7-string guitar. An interesting move, as this type of instrument has steadily lost interest among users since its peak due to the hype surrounding the nu-metal band Korn in the mid-nineties. Anyone looking for a deep tone today either chooses a lower-tuned standard guitar, perhaps a baritone guitar, for reasons of clarity, or they jump on the Djent bandwagon and devote themselves to the haptic and harmonic challenge of an 8-string instrument.

The instrument, which has a retail price of 1,159 euros, is manufactured like many other competitors in the lower and middle price segment in Indonesia, which has long since overtaken China in guitar making. The relatively young company is said to have no shortage of choice; if you include all finish variants, left-handers and basses, you end up with an impressive selection of over 150 different models. How many of these are always available, however, can only be found out in your local shop.

Woods

When it comes to choosing wood, the company is very conventional. The instrument has a full-length maple neck, which is known to provide very good sustain and is a good addition to the Evertune bridge. The neck profile is described in the documentation as C, but in my opinion it is clearly a strong D, if only because a C in the 7-string range would bring with it some limitations in terms of the grip radius.

For anyone who is not yet familiar with the Evertune system, here is a very brief summary of how it works. The system is a bridge construction that is unique in the world and uses a complex spring construction to automatically keep the instrument in tune when perfectly adjusted. You can set the system so that it always holds the target note and thus ignores or compensates for bends, for example, or you can adjust the spring tension to the string tension so that bends can be taken into account.

In addition to the advantage that the system compensates for temperature and humidity fluctuations, it also has the advantage that inexperienced musicians who do not (yet) have control over the string pressure of their left hand still have a perfectly tuned guitar when recording, so that you can find one or more guitars with this system in almost every high-quality rental studio. The disadvantage of the system is that the extensive milling work means the instrument loses sustain and bends and vibratos feel a little more indirect than with a stop tailpiece, even when perfectly adjusted. In addition, setting up the system for the first time is very time-consuming and has to be done again every time the string thickness is changed.

To give the body the necessary shape, alder wings were glued on. To support the overall black finish, an ebony fingerboard was installed, which has 24 jumbo frets and fluorescent dot inlays on the sides. There are no inlays on the fingerboard, only the eye-catching Solar Guitars logo was placed on the 12th fret for marketing reasons. To give the low B string a more defined attack, the instrument was given an extra-long scale length of 673 mm, which slightly increases the string tension compared to the long standard scale length. The Solar Guitars A1.7C G2 has 2 humbuckers made by Seymour Duncan, which are controlled by a 5-way switch that is unfortunately a bit indirect and slightly wobbly. There is also a master volume and a master tone control

The Solar Guitars A1.7C G2 in practice

What is immediately noticeable when you first play it is the high weight despite the strong Evertune bridge cutouts and the associated weight reductions. At around 3.8 kg, the instrument is still a long way from the 80s Les Paul stick, but is well above the typical Powerstrat weight class, which is usually just over 3 kg. Nevertheless, the instrument is easy to handle, which is not least due to the good ergonomics. Apart from the pointed cutaway ends, the guitar has a "flowing" shape that has no corners or edges. The comparatively wide fingerboard is also easy to grip and offers a high level of playing comfort across the entire grip area.

As expected, users who explore an Evertune bridge on an instrument for the first time will meet it with a strong frown. In the factory setting, the instrument is set to "maximum tuning stability", which means that the guitar comes tuned out of the transport box and does not go out of tune during the entire playing time. What at first glance creates a real ecstasy of joy gives way to a panicked expression on the face when you hear the first leads. Bendings? Vibrato? Everything is dead! The tone stays where it is in terms of frequency, no matter what you do with the string. Only when you pull very hard does the tone suddenly jump to the next higher semitone, and then jump up a whole tone a millimeter further. It is not possible to evenly approximate the tone by pulling the strings.

In the interests of fairness, however, I must note that I personally own a VGS guitar with the Evertune system, which is set to "regular string pulling" and copes well with normal playing, separate from my 013-056 set of strings in standard tuning. However, I left the Solar Guitars A1.7C G2 in the factory setting, as changing the system to my needs takes several hours, but it's easy to do.

In terms of sound, the Solar Guitars A1.7C G2 covers everything you want, not only but primarily, in metal. The focus is on gain, more gain and high gain, especially since the classic palm muted attacks can be easily implemented thanks to the vibrato system-free bridge construction. The pickups also have a very strong treble component to further enhance the aggression of the sound. If you really just want to play the rhythm stick and have no ambition to thicken up your playing with expressive licks, you can get very far even with the factory setting of the Evertune bridge in the typical thrash etc. range, and you don't need to pay any attention to the grip culture of your fretting hand. However, depending on the key used, a problem arises, as is also known from undamped vibrato springs of a Floyd Rose vibrato system. If you hit it hard, you hit the resonance frequency of the Evertune springs, which sounds a bit like you were using a reverb spiral in addition. For me, it was the key of "E". You can hear very clearly at the end of sound file 04 how the springs continue to vibrate, even though all the strings are dampened.

The sound files were created with an Engl Savage MKII, a Marshall 412 cabinet with Celestion G75T and two Shure SM57s.

Conclusion

With the Solar Guitars A1.7C G2, the company around YouTuber Ola Englund has a good guitar with good components. The 7-string, which is designed to be "out of the bag", allows for relaxed playing in both the low and high frequency ranges and should satisfy every part of the hard'n'heavy faction. To what extent the Evertune Bridge System suits their own playing style or hinders it, each musician has to find out for themselves.

The electric guitar has undergone countless transformations since its inception, each iteration aiming to push the boundaries of sound, playability, and aesthetics. Among these innovations, the Powerstrat stands out as a particularly significant development. Emerging in the late 20th century, the Powerstrat was designed to meet the evolving demands of rock and metal guitarists, combining the classic look and feel of the Fender Stratocaster with the power and versatility required for heavier music genres. This article delves into the origins, development, and impact of the Powerstrat, tracing its journey from concept to icon.

### The Genesis of a Hybrid Concept

The Fender Stratocaster, introduced in 1954, quickly became one of the most beloved and iconic electric guitars. Known for its sleek design, comfortable contours, and versatile sound, the Stratocaster was embraced by musicians across various genres. However, by the late 1970s and early 1980s, the rise of hard rock and heavy metal created new demands for higher output pickups, improved sustain, and more aggressive tonal options. Traditional Stratocasters, with their single-coil pickups and vintage-style tremolos, were often seen as lacking the power and durability required for these heavier styles.

The concept of the Powerstrat emerged from this context. It sought to retain the ergonomic advantages and aesthetic appeal of the Stratocaster while integrating features that catered to the needs of rock and metal players. This included the addition of humbucking pickups, advanced tremolo systems, and other modifications that enhanced the instrument’s versatility and performance.

### Early Experiments and Pioneering Models

The first significant step towards the Powerstrat came with the introduction of the Fender Stratocaster with humbucking pickups. In the late 1970s, Fender began experimenting with various pickup configurations, including models equipped with a single humbucker in the bridge position. These early models, such as the Fender Lead series, were designed to offer the higher output and thicker tone associated with humbuckers while maintaining the familiar Stratocaster shape and feel.

A crucial moment in the development of the Powerstrat was the collaboration between Fender and guitar virtuoso Eddie Van Halen. Although Van Halen is more commonly associated with his custom "Frankenstrat," his modifications to the Stratocaster platform, including the installation of a humbucker and a locking tremolo system, directly influenced the evolution of the Powerstrat. Van Halen’s innovative approach demonstrated the potential of combining traditional Stratocaster elements with modern, high-performance features.

### The Influence of Superstrats

In the 1980s, the guitar market saw the rise of "superstrats," a term used to describe modified Stratocaster-style guitars that featured advanced hardware and electronics designed for high-gain performance. Brands like Jackson, Charvel, and Ibanez led this movement, offering guitars with sleek, contoured bodies, fast neck profiles, and powerful pickups. These superstrats became the instruments of choice for many of the era’s top rock and metal guitarists, including Steve Vai, Joe Satriani, and George Lynch.

Fender, recognizing the popularity of superstrats, sought to capture this market by developing its own high-performance Stratocaster variants. This led to the creation of models like the Fender Contemporary Stratocaster and the Fender HM Strat, which incorporated features such as dual humbucking pickups, Floyd Rose locking tremolos, and sculpted neck heels for improved upper fret access. These models bridged the gap between traditional Stratocasters and the emerging superstrat trend, embodying the essence of the Powerstrat concept.

### The Powerstrat Emerges

The term "Powerstrat" itself is often used to describe Stratocaster-style guitars that incorporate high-output pickups and modern hardware. However, it was the introduction of the Fender Showmaster and the Fender American Deluxe series in the late 1990s and early 2000s that solidified the Powerstrat identity. These models were designed to offer the best of both worlds: the classic look and feel of a Stratocaster with the performance enhancements needed for contemporary rock and metal music.

The Fender Showmaster, in particular, was a significant milestone. It featured a set-neck construction (as opposed to the traditional bolt-on neck), high-output humbucking pickups, and a choice of fixed or Floyd Rose tremolo systems. The Showmaster’s design aimed to provide improved sustain, stability, and tonal versatility, making it a favorite among guitarists seeking a Stratocaster that could handle the demands of high-gain amplification and aggressive playing styles.

Similarly, the Fender American Deluxe series incorporated modern features such as noiseless pickups, S-1 switching systems for expanded tonal options, and contoured neck heels. These guitars were designed to offer professional musicians a versatile and reliable instrument that could excel in both studio and stage environments.

### Technical Innovations and Features

The defining characteristics of a Powerstrat include high-output pickups, advanced tremolo systems, and enhanced playability features. High-output pickups, particularly humbuckers, are essential for delivering the thick, powerful tone required for rock and metal music. These pickups are often paired with coil-splitting or series/parallel switching options to provide additional tonal flexibility.

Advanced tremolo systems, such as the Floyd Rose double-locking tremolo, are another key feature of the Powerstrat. These systems allow for extreme pitch manipulation while maintaining tuning stability, a crucial requirement for many modern playing techniques. The inclusion of locking nuts and fine tuners further enhances the reliability of these tremolo systems.

Enhanced playability features often include thin, fast neck profiles, jumbo frets, and contoured neck heels. These elements are designed to facilitate fast, technical playing and comfortable access to the upper frets. Additionally, the use of lightweight and resonant tonewoods helps to balance the instrument’s overall feel and sustain.

### Impact on the Guitar Industry

The introduction and evolution of the Powerstrat have had a profound impact on the guitar industry. By bridging the gap between traditional and modern design elements, the Powerstrat has expanded the versatility and appeal of the Stratocaster platform. This hybrid approach has influenced not only Fender but also other guitar manufacturers who have adopted similar design philosophies in their own instruments.

The success of the Powerstrat has also contributed to the ongoing popularity of the Stratocaster shape, ensuring its relevance in a wide range of musical genres. Guitarists who might have otherwise gravitated towards more specialized instruments have found that the Powerstrat offers a compelling combination of classic style and modern performance capabilities.

### Notable Players and Endorsements

Over the years, many notable guitarists have embraced the Powerstrat concept, contributing to its widespread acceptance and popularity. Eddie Van Halen’s influence cannot be overstated, as his modifications to the Stratocaster directly inspired the development of high-performance models. Other influential players include Yngwie Malmsteen, whose signature Stratocaster features scalloped frets and high-output pickups, and Richie Sambora, whose custom models have included dual humbuckers and Floyd Rose tremolos.

These endorsements have helped to showcase the versatility and capability of the Powerstrat, demonstrating its suitability for a wide range of playing styles and musical genres. The continued popularity of these instruments among professional musicians serves as a testament to their enduring appeal and effectiveness.

TEST: Solar Guitars A1.6D+

 Did influencer Ola Englund ever think that his guitar company Solar Guitars would be so successful when he founded it in 2017 and its models are now available in over 50 countries? The current Solar Guitars website lists what feels like over 200 different variations of the different models, which is a really large selection of instruments for an independent company. Today we have the Solar Guitars A1.6D+ Aged Natural for testing, which is very woody in the truest sense of the word.

The construction of the Solar Guitars A1.6D+ Aged Natural

The A model obviously seems to be the company's biggest revenue generator, at least with over 60 models on the website you have by far the largest selection in terms of layout and hardware. Once again we are dealing with a classic Powerstrat, although it should be noted that both the body shaping and various other details are not in the classic 80s Powerstrat style.

Rather, the instrument made in Indonesia is a more modern, slimmer version of the model, which not only has two much sharper cutaways, but also has a great deal of individuality due to the significantly higher shaping proportions. In terms of the choice of wood, we are dealing with a combination that is also often found in the Stratocaster range in terms of neck and body. In other words, we have an alder body and a maple neck, although in contrast to the Strat, the fingerboard in this case is made of ebony.

The body and neck have been stained dark, so that at first glance you have the feeling that you are dealing with a mahogany instrument. As already mentioned, the instrument has several shaping approaches, whereby apart from the typical rib protectors on the back and the armrest on the top left, the edges of the two cutaways have also been rounded off and a soft transition has been generated at the base of the neck on the back. According to the manufacturer, the shaping of the neck is a so-called C-shaping. For my part, I would still personally classify the whole thing in the D range. However, this assessment is purely subjective and everyone has to make up their own mind about it.

24 jumbo frets made of stainless steel are installed on the fingerboard, with the instrument having a scale length of 25.5 inches or 64.8 cm, i.e. the long scale length has been installed on the instrument. As fingerboard inlays, Solar Guitars once again uses the Solar Guitar logo on the twelfth fret on the Solar Guitars A1.6D+ Aged Natural and also uses the fluorescent green dot inlays on the side of the fingerboard, which start to glow when the room is slightly darkened and are a real help, especially on dark stages.

The instrument has a matt varnish and even if it doesn't sound very professional, unfortunately it's not my fault, the overall appearance reminds me a little of my grandmother's living room cupboard, which had exactly the same grain, the same stain and the same varnish.

Another nice nod to the 80s is the placement of the locking tuning machines, which are once again mirrored on the underside of the headstock in a 6 in a row style and work with a ratio of 18:1. All of the hardware on the instrument is described as distressed, which means that the metal looks slightly tarnished and is intended to simulate a certain age. Interestingly, I think this design fits very well with the solid wood section that the instrument shows.

What I really like is the detailed solution of the upper strap pin, which is located on the back part of the body. I know some manufacturers who have a similarly pointed cutaway horn on the top of the body and have drilled the strap pin somewhat irrelevantly onto the tip of the horn. Not only does it not look nice, it is also extremely unstable under vertical load. So the rear solution is much better.

The Evertune Bridge

Solar Guitars once again uses the Evertune Bridge as a bridge construction, which is known to have advantages and, in my opinion, disadvantages. For all beginners, here is a brief summary of the basic principle of the Evertune Bridge. The Evertune Bridge is a sophisticated system of springs that are installed inside the guitar and which provide counter-tension to the string tension.

The Evertune Bridge can be set so that no matter how hard you pull or press on the sides, the tone always remains the same, which ensures incredible tuning stability beyond temperature differences, humidity fluctuations or excessive finger pressure. The disadvantage of this setting is that you can no longer modulate the fretted note. This means that bending, vibrato or any kind of phrasing within the pitch is no longer possible with this setting of the Evertune Bridge. A dream for the rhythm guitarist, a nightmare for the lead guitarist.

With the second setting, after perfectly adjusting the system, you can use all the phrasing such as vibrato and bending and still enjoy the mostly very good tuning of the instrument. The disadvantage here, however, is that the response of the tone is a little more indirect when it comes to modulation and you also have to apply a lot more force to the side deflection than with a regular guitar bridge system.

The electronics of the Solar Guitars A1.6D+ Aged Natural

When it comes to pickups and electronics, Solar Guitars has once again opted for two humbuckers from Seymour Duncan for the Solar Guitars A1.6D+ Aged Natural. The models are passive Duncan Solar Plus models, which offer the most important humbucker and single coil circuits for the instrument via a five-way switch. There is a master volume and a master tone control to choose from.

The Solar Guitars A1.6D+ Aged Natural in practice

When you pick up the instrument for the first time, you immediately notice how easy the neck is to play. The neck is very easy to grip, has a pleasant feel and should suit the majority of guitarists in terms of dimensions. The body itself is also easy to handle, nestles comfortably against the body, with the respective millings serving their purpose of making handling more comfortable.

You'll notice that the instrument was primarily designed for the heavy or high-gain range as soon as you connect the instrument to the amplifier and start to use the pickups. In my opinion, the pickups lack a bit of character in the clean range that was initially set. Not that they sound bad, but they lack the liveliness of pickups from Seymour Duncan, for example, which were primarily designed for clean or crunchy sounds. In addition, the single-coil circuit is significantly quieter in terms of output level than the humbucker circuit, which is something to be taken into account, especially in the clean range.

As the level of distortion increases, however, the pickups can be quite convincing. Especially if you like the sound of passive pickups, which are known to differ significantly from active pickups in terms of their dynamics and response, the Seymour Duncan pickups manage to produce a comparatively transparent sound even at high levels of distortion, so that even at high high-gain settings the sound does not drift into muddy tones.

It is also very positive to note that the reverb spiral effect that occasionally occurred in the past and which is known from both Floyd Rose systems and the Evertune Bridge did not appear on this instrument. This made it possible to obtain a transparent sound even at high high-gain settings and corresponding palm-muted riff attacks.

Overall, the instrument is certainly convincing and will certainly bring a lot of joy to its target group. The extent to which the Evertune Bridge can be used effectively is up to each individual, as is whether or not they prefer a purely wooden look. Personally, I left the Evertune bridge as it was set at the factory, i.e. in the "balanced position", which was a bit strange for me, as any form of vibrato or modulation that I normally have in my playing was balanced out and eliminated by the system. But as is often the case, it's all a matter of personal taste.

The sound files were created with an Engl Savage MkII, a Marshall Cabinet 4x12 equipped with a Celestion G12 75T speaker and two Shure SM57.

Conclusion

With the Solar Guitars A1.6D+ Aged Natural, the manufacturer has a good instrument for the hard'n'heavy sector in its portfolio. Anyone looking for an instrument with an Evertune bridge for this music segment should take a look at this instrument.

Additional Informations:

In the realm of musical instruments, particularly electric guitars, innovations are often greeted with a mix of enthusiasm and skepticism. Among such advancements, the Evertune bridge stands out as a revolutionary solution to one of the most persistent challenges faced by guitarists: maintaining perfect tuning stability. This article delves into the origins, development, and impact of the Evertune bridge, highlighting its journey from a conceptual innovation to a game-changing component in modern guitar design.

### The Conceptual Genesis

The Evertune bridge was conceived by Cosmos Lyles, an engineer with a passion for music and a deep understanding of mechanical systems. The idea originated from the frustration that many musicians experience with the constant need to retune their instruments, especially during live performances and recording sessions. The aim was to create a bridge system that could keep a guitar in perfect tune regardless of environmental changes, playing style, or string wear.

Lyles' initial concept was to design a mechanical system that could compensate for the factors causing a guitar to go out of tune. These factors include temperature and humidity changes, string stretching, and variations in playing pressure. The challenge was to create a system that was both precise and reliable, yet simple enough to be integrated into standard guitar designs without significantly altering their appearance or playability.

### Prototyping and Development

The development of the Evertune bridge involved extensive research and numerous prototypes. Lyles collaborated with a team of engineers and musicians to refine the design. The key innovation of the Evertune system lies in its use of springs and levers to dynamically adjust the tension of each string. This mechanism ensures that the strings maintain consistent tension, thus keeping the guitar in tune.

The initial prototypes faced several challenges, including ensuring the durability of the system under rigorous playing conditions and maintaining the tonal quality of the guitar. Through iterative testing and feedback from professional guitarists, the design was gradually perfected. The final version of the Evertune bridge featured a series of individual modules for each string, allowing precise adjustments and easy maintenance.

### Market Introduction and Reception

The Evertune bridge was officially launched in 2010, marking a significant milestone in the field of guitar technology. Its introduction was met with cautious optimism from the guitar community. Musicians and industry experts were intrigued by the promise of a guitar that could stay perfectly in tune, but there were also concerns about the potential impact on the instrument's sound and playability.

To address these concerns, Evertune engaged in extensive demonstrations and endorsements by professional guitarists. Notable musicians such as Gus G (Ozzy Osbourne, Firewind) and Scott Ian (Anthrax) were among the early adopters who praised the bridge for its reliability and consistency. These endorsements helped to build credibility and trust within the guitar community.

### Technical Specifications and Functionality

The Evertune bridge operates on a simple yet effective principle: maintaining constant tension on each string. Each string passes through a spring-loaded saddle that adjusts automatically to changes in tension. This mechanism compensates for any factors that would typically cause a guitar to go out of tune, such as bending strings, heavy strumming, or environmental changes.

One of the key features of the Evertune bridge is its ability to be fine-tuned for different playing styles. Musicians can set the system to allow a certain amount of bending for expressive playing, or to lock the tuning entirely for maximum stability. This flexibility makes it suitable for a wide range of musical genres and playing techniques.

The Evertune bridge is designed to be installed on both new guitars and as a retrofit on existing instruments. This versatility has contributed to its growing popularity among both manufacturers and individual musicians. Brands like ESP, Schecter, and Gibson have incorporated Evertune bridges into some of their models, further solidifying its acceptance in the industry.

It has challenged the traditional notion that guitars inherently require frequent retuning, offering a practical solution to a longstanding problem. This has not only improved the performance experience for musicians but also opened up new possibilities for guitar design and engineering.

One of the significant benefits of the Evertune bridge is its contribution to the recording process. In the studio, maintaining consistent tuning can be a time-consuming task, often requiring multiple takes to ensure perfect pitch. The Evertune system minimizes this issue, allowing for more efficient recording sessions and reducing the need for post-production pitch correction.

Moreover, the Evertune bridge has influenced the design philosophy of modern guitars. Its integration requires precise engineering and manufacturing, pushing guitar makers to adopt higher standards of quality control. This has led to advancements in other areas of guitar construction, as manufacturers strive to complement the stability provided by the Evertune system with equally high-quality components.

### Challenges and Criticisms

Despite its many advantages, the Evertune bridge is not without its critics. Some guitarists argue that the mechanical system can alter the natural feel and response of the strings, particularly when it comes to expressive playing techniques like vibrato and bending. While the system can be adjusted to allow for some bending, purists often prefer the traditional feel of a standard bridge.

Another criticism is the complexity and cost of installation. Retrofitting an existing guitar with an Evertune bridge requires precise routing and setup, which can be challenging and expensive. This has limited its adoption among amateur guitarists and hobbyists who may be deterred by the additional expense.

### The Future of Evertune

Looking ahead, the future of the Evertune bridge seems promising. Continued advancements in materials and manufacturing techniques are likely to enhance the system's performance and affordability.
