At half the size of a standard wah, this Crybaby provides the perfect balance of wah control, pedalboard efficiency and onstage convenience. Now you can get the dynamic versatility and space-saving footprint with the ultimate mod for convenient live performances - auto return switching. With just four controls, you can radically alter your instruments voice. First, the range selector allows you to choose from the four most popular sweep ranges. Next, the Q control allows you to shape the response of the wah effect. Finally, the volume knob and boost switch allow you to bump your signal straight to the front of the mix when its time to solo. A convenient LED lets you know when boost is engaged. Auto return switching allows you to add expression wherever you need it; push down on the toe of the pedal to engage the effect and back off to disengage it. This pedal comes in at half the size of a standard Crybaby, and on the inside, it sports the legendary red Fasel Inductor. This pedal belongs on your pedalboard. True hardwire bypass. Powered by 9 volt battery or AC adaptor (ECB003).
