Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic Keeley squeeze with studio-smooth sustain and added clarity. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in everything from subtle leveling to punchy country snap. Standard 1/4" in/out, 9V DC center-negative power, and true-bypass-style performance for a clean signal path. A trusted compressor for guitarists who want consistent dynamics without sacrificing tone.
