Used Keeley 4 Knob Compressor Effect Pedal

This used Keeley 4-Knob Compressor is in great condition and delivers smooth, studio-style compression that enhances sustain and clarity for guitar or bass. Simple controls for Sustain, Level, Attack, and Clipping let you dial in everything from subtle leveling to punchy squeeze with added harmonic edge. Built in a rugged stompbox enclosure, it runs on standard 9V DC power and features true-bypass switching for a clean, unaffected tone when off.
