Used Keeley 4 Knob Compressor Effect Pedal

This used Keeley 4 Knob Compressor is in great condition and delivers classic studio-style compression for tighter, more expressive tone. Easy four-control layout (Sustain, Level, Attack, Clipping) lets you dial in everything from subtle smoothing to punchy sustain, with a popular clipping switch for added character. Built in a rugged compact stompbox format, it runs on standard 9V DC power and is ideal for guitar or bass rigs needing consistent dynamics and enhanced note clarity.
