Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squeeze that adds sustain, clarity, and punch to guitar or bass. Simple 4-control layout for dialing in the perfect feel: Sustain, Level, Attack, and Clipping. Built in a rugged stompbox enclosure with standard 1/4" in/out and 9V DC power operation, it’s an easy drop-in upgrade for cleaner chords, tighter funk, and smoother leads.
