New, Unused JHS Pedals The AT+ JHS Pedals I never ended up using it after I bought it! It's a new, unused item. From "JHS Pedals," comes the Andy Timmons model based on the Angry Charlie! The AT+ is a 2-in-1 pedal that couples an independent booster to the front end without changing the controls or sound nuances of The AT. Power: Center-negative DC9V-18V adapter (※Batteries not supported)
