EarthQuaker Devices Chelsea
EarthQuaker Devices · pedal
The EarthQuaker Devices Chelsea is a waveform manipulator and treble booster from EQD, designed to add pronounced presence, high-end harmonic enhancement, and dynamic drive character to the signal. The Chelsea operates in the treble booster tradition popularized by vintage units used with vintage British amplifiers, and adds a harmonically rich, present character that brightens and energizes the signal before it reaches the amplifier. It suits players who want the bright, forward, harmonically complex enhancement of a treble booster in a modern, reliable enclosure, applicable to blues, classic rock, and vintage-voiced applications.
