Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squeeze that keeps your tone smooth, punchy, and articulate. Simple four-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle leveling to rich sustain. Built in a rugged compact stompbox with standard 1/4" in/out, true-bypass switching, and 9V DC center-negative power for pedalboard-friendly operation.
