Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in excellent condition, delivering the classic studio-style squeeze that made this pedal a go-to for guitarists. Four intuitive controls (Sustain, Level, Attack, and Clipping) let you dial in everything from subtle smoothing to punchy, country snap with enhanced clarity. Built for standard 9V DC pedalboard power with true bypass switching, it adds quiet, musical compression, improved sustain, and tighter dynamics without sacrificing your tone.
