Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor pedal in great condition, delivering classic studio-style compression for guitar or bass with enhanced sustain, clarity, and touch sensitivity. Simple 4-control layout (Level, Sustain, Attack, Clipping) makes it easy to dial in anything from subtle leveling to punchy squish. Built in a rugged compact stompbox enclosure with true bypass switching and standard 1/4" input/output. Powered by 9V DC center-negative adapter (or 9V battery on many units).
