Auto Wah pedal effect. Now you can get the sound of a fixed-position Cry Baby® Wah in a standard pedal box. With the Cry Baby Q Zone Fixed Wah-voiced by the famous red Fasel® Inductor- there's no need to mess around with the rocker and try to listen for the sweet spot every time you go onstage. Just dial up the sound you want and kick the switch. This pedal has four controls to help you customize your sound. The Boost control allows you to increase your effect signal by up to +16dB. The Bandpass knob sets center of selected frequency range, which takes the place of the rocker in a Cry Baby Wah. The Range switch allows you to select a High, Middle, or Low frequency range. The Q ADJ knob controls bandpass width. Finally, the Expand knob controls the effect's low end and gain level. The Cry Baby Q Zone Fixed Wah provides the rich, resonant vocal tones of a fixed wah with even more control over your sound and the convenience of a stompbox.FeaturesInstant fixed-wah sound with a kick of the footswitchClassic resonant, vocal tone used on many classic recordingsUpgraded for even more control over your fixed wah soundFeaturing classic red Fasel Inductor
