Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—an industry-standard compressor that delivers smooth sustain, added punch, and studio-style control for guitar and bass. The simple 4-knob layout lets you dial in Level, Sustain, Attack, and Clipping for anything from subtle leveling to tight, squashed compression. Built in a rugged compact enclosure with true bypass switching and standard 1/4" input/output, it runs on 9V DC pedal power for easy integration on any board.
