Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition, delivering classic studio-style compression in a compact pedal. Simple controls for Sustain, Level, Attack, and Clipping let you dial in everything from subtle smoothing to punchy, squashed sustain while preserving pick dynamics. True-bypass switching keeps your tone intact when off, and its rugged enclosure is ready for gigging. A go-to choice for guitar or bass players wanting tighter cleans, added sustain, and consistent volume.
