Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—classic, studio-smooth compression for guitar and bass with the clarity and sustain Keeley is known for. Simple 4-knob layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle leveling to singing sustain and punchy country snap. Built in a rugged compact stompbox enclosure with true bypass switching, standard 1/4" in/out, and 9V DC power.
