Used 2020s Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in excellent condition, delivering classic studio-style compression in a compact pedal. Four intuitive controls (Sustain, Level, Attack, and Clipping) let you dial in anything from subtle leveling to punchy, squashed sustain, while the true-bypass design keeps your tone intact when off. Runs on standard 9V DC center-negative power for easy pedalboard integration. A go-to choice for tightening cleans, boosting solos, and adding smooth sustain.
