Named after the guitar shop in which it was purchased back in 1989, the Chelsea recreates all the idiosyncrasies of the original but without the threat of total collapse. With only three controls, this deceptively powerful pedal offers you everything from light overdrive to full on distortion with all the clarity and blissful grinding that make the original so special. Just like the original, 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. This thing is deep and will cover pretty much anything you can throw at it. Trust us, we are all professionals here. We promise.
