Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—an iconic, studio-style compressor for clean, country, funk, and soaring lead tones. Simple controls (Sustain, Level, Attack, Clipping) let you dial in anything from subtle smoothing to punchy, squashed sustain while keeping your pick attack intact. Compact stompbox format with true-bypass switching, standard 1/4" in/out, and 9V DC power (center-negative) for easy integration on any pedalboard.
