Gary was dreamt up by the one and only Lee Kiernan from the band Idles and started as a simple request to create a compact version of the now discontinued Gray Channel, which was a mainstay on Lee's board, but with a deeper look into his dark side. Gary's right brain is a ripping fuzz tone with an envelope-controlled variable pulse width and enough volume to blow everything up. It turns the signal into a square wave and allows you to dynamically adjust the duty cycle with pick attack. Yes! Controls the sensitivity of the envelope. All the way down gets you a thick and heavy square wave fuzz tone that will sustain for days and go dead quiet when you stop playing. As you increase the Yes! control, the envelope becomes more interactive, and the pulse width narrows the harder you hit it. As the pulse width narrows, the tone becomes more nasal and biting. In other words, with higher sensitivity settings, the sound will disappear entirely and come cruising back to Gary's big guy tone. With proper playing dynamics, this creates a very cool effect that can sound like an exploding amp coming in and out of life, blown through a phase shifter. This effect can also be controlled with an expression pedal for manual operation or for finding just the right pulse width. When using an expression pedal, Yes! sets the peak of the sweep. Oosh acts as the master volume and has an insane amount of volume on tap! Gary's left brain is a simple and natural sounding overdrive that keeps your tone lively and drives your amp crazy. It is based on the green channel of our Gray Channel, which is our take on the classic little yellow overdrive that started it all for us. Lee used this pedal with the clipping switch permanently set to the middle position, which removes all the diodes from the circuit, producing a full-bodied, cutting opamp distortion with plenty of volume on tap. We have reproduced that tone here with exacting precision. Go sets the opamp drive and can range from a simple full-range clean boost all the way up to a smooth and natural distortion. In conjunction with That's It, which is the master volume for the drive side, you can use Gary's softer side as a clean boost to push your amp into overdrive or turn up Go and use all of Gary's internal magic to create the finely tuned dirt you desire. Gary's signal path is fuzz into overdrive for total tonal integrity and cannot be changed. - Developed with Lee Kiernan from the band Idles! - Dynamic pulse width modulated fuzz paired with a natural-sounding op-amp overdrive. - Fuzz pulse width modulation is dynamically controlled by the on-board envelope or an external expression control. - Yes!" Controls the sensitivity for the envelope or sets the pulse width limit when using an expression pedal. - "Oosh" is the master volume for the fuzz. - Overdrive section from the legendary and sought-after Gray Channel, capable of producing thick, full distortion or for use as a clean boost. - "Go" is the gain control for the overdrive. - "That's It" is the master volume for the overdrive. - All-analog signal path - True bypass - Silent relay-based switching with Flexi-Switch® Technology - Lifetime warranty"
