Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic Keeley sustain and smooth, studio-style compression for guitar or bass. Simple 4-control layout lets you quickly dial in Level, Sustain, Attack, and Clipping/Blend-style tone shaping (model-dependent), from subtle sweetening to punchy squish. Rugged, pedalboard-ready enclosure with true-bypass switching and standard 9V DC center-negative power for easy integration into any rig.
