Used Keeley 4 Knob Compressor Effect Pedal

This used Keeley 4 Knob Compressor pedal in excellent condition delivers smooth, studio-style compression for guitar, adding sustain, clarity, and punch without sacrificing your tone. The simple 4-control layout (Sustain, Level, Attack, and Clipping) makes it easy to dial in anything from subtle leveling to country snap and singing leads. Built in a rugged compact enclosure, it runs on standard 9V DC power and features true bypass switching for a clean, uncolored signal.
