Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—classic studio-style squash and sparkle for guitar or bass. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in everything from subtle leveling to country snap. Built in the USA with rugged metal housing, true bypass switching, and standard 1/4" in/out. Runs on 9V DC center-negative pedal power for easy integration on any pedalboard.
