Used Keeley 4 Knob Compressor Effect Pedal

This used Keeley 4 Knob Compressor delivers the classic studio-style squeeze guitarists love, with controls for Sustain, Level, Attack, and Clipping to dial in everything from subtle leveling to punchy country snap. Built in a rugged compact stompbox format with standard 1/4" input/output and 9V DC power, it’s an easy fit on any pedalboard. Fair condition shows noticeable cosmetic wear and signs of use, but it’s ready to add smooth dynamics and enhanced sustain to your tone.
