With only three controls, this deceptively powerful pedal offers you everything from light overdrive to full on distortion with clarity and blissful grinding. A Tone On/Off switch allows you remove the Tone control from the circuit, opening up a whole new world of midrange grind. Switch it off for a simplified and straightforward attack or leave it on for a full-bodied distortion with loads of low-end with a slight natural scoop. Roll up the Sustain for wall-shaking bass notes or sustaining lead and adjust the Tone for a wild and wide frequency response from aggressive top end to low-end rumble.

CONTROLS

Sustain: Adjusts the amount of distortion and sustain.

Tone: Use this to fine tune the frequency response. Boost treble by turning clockwise, boost bass and tame the top end by turning counterclockwise.

Tone On/Off: This switch bypasses the tone control and delivers a more mid focused response.

Level: Controls the output volume.

Power
This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
