One pedal; two effects. If you like to play it safe, this pedal is not for you. It combines two different effects; phase shifter and envelope filter, into a single dangerous machine. This pedal cranks out an array of off-kilter sounds, twisting your riffs into crazy new forms. Bee stings, perfect for funky moods. Gloopy syrup to drench your low-string twanging. Fifty shades of rude behavior thatll turn a pleasant cocktail party into a drunken brawl. And by the way, its bratty attitude works great with electric bass as well as guitar. If youre looking for a pedal that smiles politely and behaves appropriately, keep right on walking-you wont find it here. But if you seek a kindred spirit and fellow troublemaker, this might just become your new best friend. True hardwire bypass. Powered by a 9 volt battery or AC adaptor (ECB003) - not supplied.
