Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squeeze that keeps your tone smooth, punchy, and articulate. Simple four-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle leveling to rich, singing sustain. Built for standard guitar/bass rigs with 1/4" in/out and true-bypass switching, it runs on a 9V battery or standard 9V DC center-negative power supply.
