Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor pedal in Good condition, delivering classic studio-style compression and enhanced sustain for guitar or bass. Simple four-control layout lets you dial in Level, Sustain, Attack, and Clipping/Blend-style character for everything from subtle leveling to punchy, country snap. Built in a rugged compact enclosure with standard 1/4" mono input/output and 9V DC center-negative power. A go-to compressor for clean tones, funk rhythm, and soaring leads.
