EarthQuaker Devices Chelsea Low End Fuzz Driver

The EarthQuaker Devices Chelsea is a rugged, no-nonsense fuzz pedal born from a storied past and rebuilt for the modern player. Based on a one-of-a-kind unit that found its way into the hands of James Murphy (LCD Soundsystem), this beast has delivered crushing bass fuzz on global stages and iconic recordings alike. Now, it returns—refined, reliable, and ready to roar.

With just three intuitive controls, the Chelsea delivers a huge spectrum of distortion—from gritty overdrive to full-throttle fuzz. The Sustain control dials in everything from tight punch to endless sustain, while the Tone knob (which can be bypassed via the Tone On/Off switch) allows you to sculpt your mids, highs, and lows. Turn it off for a raw, mid-forward bite, or leave it on for full-spectrum chaos with a natural low-end scoop.

This pedal is all about contrast—massive yet clear, simple yet sonically rich. It has the ability to stay articulate or blur into fuzzy oblivion. Built to replicate the exact tone of its vintage predecessor without the fragility, the Chelsea is an uncompromising fuzz designed for bass, guitar, and beyond.
