With only three controls, the deceptively powerful Earthquaker Chelsea Low End Fuzz Driver Pedal offers you everything from light overdrive to full on distortion with clarity and blissful grinding. A Tone On and Off switch allows you to 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.

The Sustain adjusts the amount of distortion and sustain. The Tone On and Off switch bypasses the tone control and delivers a more mid focused response. Tone is used to fine-tune the frequency response. Boost treble by turning clockwise, boost bass and tame the top end by turning counterclockwise. Level controls the output volume.
