Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in excellent condition, delivering the classic studio-style squeeze guitarists love. Simple, powerful controls—Sustain, Level, Attack, and Clipping—let you dial in everything from subtle leveling to rich, punchy sustain with enhanced clarity and feel. Built in a rugged compact stompbox enclosure with true-bypass switching, standard 1/4" in/out, and 9V DC power (center-negative), it’s a reliable upgrade for clean tones, country snap, funk rhythm, and singing leads.
