Modern, high-gain transistor fuzz. And this thing is LOUD!!! It can handle anything from smooth distortion to over-the-top nasty fuzz. The three-position toggle switch takes the pedal from normal fuzz tones in the right position to a gated, splatty feel with fizzy decay in the left position, all while remaining musical and useful. The middle position takes you into synthy video game territory and lets the notes “bloom” slightly during the sustain. And for a more fizzy note decay, roll back on your guitar’s volume knob! Use the starve control to affect the voltage supplied to the circuit – depending on the toggle setting this can either smooth out the higher gain settings or enhance the sputters and splats. Playing higher up the neck can even cause an octave up effect! The starve, fuzz, and toggle are all very interactive, making for tons of tonal possibilities.
