Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—an industry-standard stompbox for smooth sustain, tighter dynamics, and sparkling clean tone. Simple 4-knob control layout (Sustain, Level, Attack, Clipping) makes dialing in everything from subtle leveling to punchy, country-style snap fast and musical. Built in a rugged compact enclosure with true bypass switching and standard 1/4" input/output jacks, it runs on 9V DC pedal power for easy integration on any board.
