The Duality Dual Fuzz from Darkglass Electronics offers not one but two distinct fuzz circuits, which can be blended any way you choose with your clean signal, therefore creating a whole range of fuzztone filth.

Classily presented in a brushed silver matte finish with a mirror chromed top facing, the four black controls all turn reassuringly smoothly while the stomp button is solid and firmly operated: the whole pedal is evidently built to last.

The Blend control ranges from a clean signal when turned fully left to a positively dripping fuzztone when panned fully right, although it is possible to hear both the clean and effected signals simultaneously. Level adds grit and distortion, while the Filter control increases the resonance, top end clarity and definition.

Impressively, articulation is never lost with this pedal, although if  you prefer to lessen the high-end characteristics (we're after fuzz, not fizz, after all), roll off the Filter control to your preference as any dodgy fretting or mistakes will stand out like a sore thumb. Warm and rich, just as a great fuzz pedal should be, the power and aggression which this pedal is able to conjure up is mightily impressive.

Super Intelligent Footswitch

Super Symmetry (Silver)

The Microtubes Vintage is our tribute to some of the most legendary sounds in rock history. It provides warm tube-like tones with a natural dynamic response that echoes the organic compression of old tube amps and reel-to-reel tape machines.

Vintage Microtubes

The Intelligent Footswitch is an intuitive yet versatile accessory for our amplifiers. One tap will engage and disengage the Microtubes Engine, while holding for 3 seconds will Mute the amplifier. It is connected to the head via a standard 1/4″ cable and it’s powered by a microcontroller that sends commands to the head using a proprietary communication protocol.
