The EHX Cock Fight Plus offers up the award-winning tone of the original Cock Fight in a rugged, lightweight pedal and with a traditional rack and pinion style operating mechanism. It contains two different expressive filters: a traditional wah pedal filter and a formant filter used for vowel sounds. The Cock Fight also features a lively fuzz section that can be added before or after the filter section, or taken out of the signal path completely. Great wah and talking pedal sounds. Use with or w/out the fuzz. Place the fuzz before the filter for a vintage vibe or after for a more modern sound. Adjustable bias control takes the fuzz from "normal" to a classic "dying battery" sound. 9Volt battery included, also works with optional EHX 9.6DC200mA power supply.
