This Cry Baby Wah captures the throaty, expressive sound of the original wah pedal, featuring a Halo™ Inductor and thru-hole components with a premium pot, switch, and jacks. This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
