Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squeeze and added sustain that makes guitars shine. Simple controls for Sustain, Level, Attack, and Clipping let you dial in anything from subtle leveling to punchy, articulate compression. Built in a rugged compact enclosure and powered by standard 9V DC (center-negative) or a 9V battery, it’s a go-to pedal for clean tone, country snap, and smooth lead lines.
