Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squeeze and sparkle guitarists love. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in smooth leveling, added punch, or bright country snap without killing dynamics. Built in a rugged, pedalboard-ready enclosure, it runs on standard 9V DC power and fits comfortably in any signal chain for clean, quiet compression and enhanced sustain.
