TEST: Positive Grid Bias Distortion

 One would think that everything that needs to be said about distortion pedals has been said. Strictly speaking it is. Anyone who owns a TS-9, an OD-1 or a Big Muff knows what they have and in which context they want to use this sound. The downside is that over the years up to 20 or more booster, overdrive, distortion or fuzz pedals accumulate on the home floorboard, which not only all want to be mounted and supplied with power, but also one does not tear a hole in your personal pedal budget that is to be underestimated.

Many multi-effects boards have been trying to remedy this for decades, some better, some worse, but they all have one thing in common. Apart from the common parameters such as tone, gain or volume, possibly paired with a three-band tone control, the user cannot change much on the supplied preset. I like it, I don't like it, do it or die!

The Positive Grid Bias Distortion Pedal takes a different approach here. Designed at first glance as a comprehensive floor pedal of the classic kind, what is probably the most powerful software tool currently available from a pedal manufacturer slumbers in the background. The basic presets can be bent beyond recognition, and existing distortion pedals can be recreated and saved using the tone matching known from the Positive Grid Bias Head.


conception

The Positive Grid Bias Distortion Pedal has 20 presets in its starting basis, which can be selected via an endless control. By pressing the button for a longer period of time, you can assign the previously set sounds to one of the three foot switches. Attention, the switches are comparatively close together, and there is no mechanical protection for the potentiometers above them, which means trampling with biker boots inevitably leads to incorrect operation of the pedal! The fourth switch on the right is a boost controller, which is infinitely variable in intensity and has a triple sound characteristic (treble, clean, fat) via a mini switch.

The Positive Grid Bias Distortion receives its operating voltage from a supplied multi-voltage/multi-plug power supply unit, which works worldwide and supplies the pedal with power via the USB port. In an emergency, there is also a classic 9V power socket with an additional adapter. MIDI In/Thru and an expression pedal input allow additional external management.

In terms of operation, we find old acquaintances again with gain, level and a three-band tone control, only the blend control makes us sit up and take notice. Here you can continuously crossfade the mixing ratio between the dry distorted signal and the processed signal in the output stage. "Huh? Where am I supposed to be able to set something like that?” At this point at the latest, the inclined reader will notice that the positive grid bias distortion is a completely different concept than what most of us are used to. And what is the purpose of the WLAN sign including the glowing LED on the back of the housing?


Practice

In order not to overwhelm the user, Positive Grid first emulated copies of the most common distortion pedals, such as Ibanez TS9, Boss DS1, BK Butler Tube Driver, Fulltone OCD, Roger Mayer Voodoo1, Boss Metal Zone, EHX Big Muff, ProCo Rat, Voodoo Lab Sparkle Drive, Boss DS2 Turbo, Fulltone Fulldrive, Voodoo Lab Super Fuzz, Roger Mayer Spitfire and the MXR Fuzzface. To say it straight away, these are references to the originals, if you expect a perfect clone here you will be disappointed.

However, you have the option of using the Tone Match method to recreate a distortion device of your choice using predefined modules, which works surprisingly well. Only response and playing feel varied a little depending on the pedal type. However, the big aha effect opens up when you start the software, which is available for MacOS/PC and iPad. Not to be beaten optically, you can now exchange or modify the basic components down to the smallest detail. It doesn't matter whether it's the configuration of transistors, high-pass or low-pass filters, attack, release, output stages, almost all parameters of the inner workings of a distortion device can be varied, which leads to an almost endless variety.

The pedal communicates with the computer / iPad via Bluetooth and saves the specified sounds including a personal look. Visually, the system is unbeatable. Great cinema with a large play instinct promotion is announced here. In terms of sound, the result depends heavily on the equipment used. A single-channel all-tube amp that is as neutral as possible offers the best opportunity to try out the different sounds with its clearly structured basis. Unfortunately, many editing options also offer the possibility of screwing past the desired result, so you should take a lot of time and give your ears a rest from time to time.




Conclusion

The Positive Grid Bias Distortion Pedal opens up endless possibilities for the ambitious distortion nerd. Using the supplied software, personal sound requests can be bent down to the last detail and create pedal types that are not yet available in this form from any manufacturer.

Try it out and bring plenty of time!
