Used Keeley 4 Knob Compressor Effect Pedal

Smooth, studio-style dynamics in a pedal: this used Keeley 4 Knob Compressor is in great condition and delivers the classic Keeley squash with plenty of clarity and sustain. Simple 4-knob control layout (Level, Sustain, Attack, and Clipping/Blend depending on revision) makes it easy to dial in everything from subtle leveling to country snap. Standard 1/4" in/out and 9V DC power operation for easy pedalboard integration.
