Used Keeley 4 Knob Compressor Effect Pedal

This used Keeley 4 Knob Compressor pedal in good condition delivers smooth, studio-style compression for guitar and bass, adding sustain, clarity, and punch without sacrificing your natural tone. Simple controls for Sustain, Level, Attack, and Clipping let you dial in everything from subtle leveling to tight, snappy country squish. Built in a rugged stompbox enclosure with standard 1/4" input/output and 9V DC power, it’s an easy upgrade for any pedalboard.
