Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition, delivering the classic studio-style squeeze players love for clean electric or bass. Dial in the perfect feel with four simple controls: Sustain, Level, Attack, and Clipping, for everything from subtle leveling to snappy, punchy compression. Built in a rugged stompbox enclosure with standard 1/4" in/out and 9V DC power, it’s an easy upgrade for tighter dynamics, added sustain, and polished tone on any pedalboard.
