TEST: Blackheart Little Giant

 What would the classic rock guitarist be without a matching all-tube amp? On the one hand, the sound is significantly limited and mercilessly subjected to “semiconductor servitude” ;-), but on the other hand, it also suffers from a few back problems. Along with dynamic response, smooth distortion and powerful performance, the heads of the sonic Bundesliga, together with their colleagues from the cabinet department, unfortunately also share the title of “number one disc killer”. Anyone who has ever been able to heave their full stack alone from the basement into their station wagon towards the rehearsal room knows what I'm talking about...

Aware of this problem, some manufacturers have responded and have recently brought an increasing number of small and miniature amps onto the market, which can easily hold a candle to a transistor practice amplifier in terms of size and transportability, but not without foregoing the sonic attributes of a full tube amp want. In addition, these amplifiers put you in the position of being able to finally drive the power amplifier to full saturation at club shows without getting suspicious looks or harsh curses from the F.O.H. mixer.

One of these representatives is the Blackheart “Little Giant 5”, which I have available for testing as a half stack with the matching Speaker Cabinet BH112. The Blackheart company, like the “Crate” label, belongs to the LOUD amplifier group, which can be seen from a small reference on the front panel of the amp. Russian amplifier expert Pyotr Belov is the mastermind in Blackheart's development.


Construction:

“My God, how cute..”! These are inevitably the first words that come to mind when you peel the little guy out of the packaging. Even my wife couldn't help but say, "That's cute." In view of the usual top part weight class of up to 30 kg and more, the 9.5 kg that the “little giant” weighs seems more than tame. In addition, its dimensions of 24.3 cm x 38.1 cm x 22.8 cm (H x W x D) make it an easy-to-transport individual that easily fits into any footwell in a car. The matching cabinet, weighing 13.5 kg and measuring 47.3 cm x 46 cm x 28 cm, is also easy to handle in terms of transport.


The Blackheart Amp, like the cabinet, is equipped with a coarsely structured and durable vinyl cover. Plastic corner protectors also protect the edges of the housing. In addition to the company logo, there are on/off switches on the front (no standby switch!), a switch between triode (3 watts) and pentode switching (5 watts), an oversized on/off light, and a spartan three-band tone control and a single volume control.

There are 5 different speaker connections on the back (2x 4 ohms, 2x 8 ohms, 1x 16 ohms), which alone fill half the panel, along with a power plug connection for cold devices.

The interior of the amplifier is also technically reduced to the bare essentials. Only two tubes are responsible for the amplification process. On the one hand, a 12AX7/ECC83 in the preamplifier and a single EL84 in single-ended operation in the power amplifier. A complete tube change is correspondingly inexpensive with this little guy.

The closed BH112 cabinet is built from 18 mm plywood and has a rear-mounted 12" Eminence speaker, which is built specifically for Blackheart and is designed for 16 ohm impedance. There are also two jack sockets connected in parallel on the back for connecting several speakers in parallel.

The workmanship of all components is flawless, everything is neatly glued, screwed tightly and wired clearly. Nothing to complain about, nothing to complain about.


Practice:

“3 watts? 5 watts? "What kind of performance data are these?" one or the other will ask themselves, "does anything actually come out of it, my car radio has more output power, you know".... Let's immediately cover this comparison with a cloak of silence!

First of all, you should keep in mind that in order to double the volume, the power of the amplifier must be increased tenfold (!), a 300 watt amplifier, for example, is only twice as loud as a 30 watt amplifier or four times louder than the Blackheart in triode mode! There is also the subjective effect that 3 or 5 watts of tube power are significantly louder than analog transistor power, mind you, purely subjective. Anyone who has ever opened up a 30 watt all-tube amp knows how incredibly loud an amp can sound in the rehearsal room, provided it is equipped with the appropriate loudspeaker department. So what about the Blackheart's minimalist performance specifications? Loud, I can only say, really loud! You shouldn't believe how big a face the dwarf has if you just give him a good hard time, but everything in order.

After switching on the device, the large operating light shines at you with the brightness of a moped taillight. In general, there seems to be a trend towards bright operating lights in the scene. If this continues, you can leave the lighting system in small clubs at home in the future ;-) After a short warm-up phase of the tubes, you can get started. In triode operation, the amp experiences quite high, but still transparent, compression even at low volumes. The lack of push-pull circuitry also seems to make the sound a little more compact. In combination with the closed cabinet, the Blachheart sounds unexpectedly grown-up, which means that the attack and response are in good proportion to much larger amps. There are slight comparisons to the AC30, which is surprising given the tube configuration, but there is even a bit of Bluesbreaker in the feel. However, you can't get the amp really clean, the first slight crunch starts at volume settings above 2 and, thanks to the lack of a master volume, there is nothing with separate gain in the preamp. There is a continuous, even distortion up to the maximum limit, with “AC/DC crunch” being the end of the gain. You won't find high gain with this amp. The Little Giant reacts very nicely with various distorting pedals and reproduces the respective orientation of the pedal in great detail.

In pentode mode, the amp takes a significant step forward in terms of volume. The additional screen grille provides the head with a significantly tighter sound, less compression and better dynamics. At this point at the latest you can keep up with a drummer who plays powerfully, although you shouldn't forget that 5 watts in a larger club will actually be released into thin air in terms of pressure. However, in small clubs or in the rehearsal room, the head can fully demonstrate his strengths. What a practical feature it would be if you could choose between these two sounds with a footswitch; rhythm and solo sounds would be almost perfectly coordinated in two presets. However, it is questionable whether the power amplifier will continue to do this without complaint over a longer period of operation.....



Conclusion:

But oops, who would have expected this dwarf to have such a cheeky demeanor? With the matching 112 Cabinet you have a half stack at hand that not only looks cute, but is a serious workhorse in live operation. However, flexibility is a foreign word here. 2 sounds, depending on the power amplifier operation with continuous distortion from “slightly scratchy” to “British-pressing”. OK, clean sounds can also be achieved with the volume control turned down, but if you expect a “twin reverb clean”, you’re in a lost cause with the Little Giant. With a second cabinet upgraded to a full stack, you don't have to hide in any club and as I said, with which amp can you drive the power amplifier completely to the right during the entire show without having to go to the hearing aid acoustician after the show.
