The Dunlop Cry Baby 535Q Multi-Wah Pedal allows you to customize and shape the sound of the wah. It takes you from a narrow, sharp wah to a broad, subtle wah with a simple turn of the Q dial. Also offers 6 guitar wah ranges with a variable boost from 0 to +16dB and a hard-wired on/off switch. New custom circuitry consumes less power and eliminates unwanted distortion. EC.
