New Tech 21 SansAmp Roto Choir Guitar Effect Pedal! Free Fender Cables! Includes Fender Custom Shop 10 Foot Tweed Instrument Cable and 2 Fender Custom Shop Tweed Patch Cables! Custom, silent-switching actuator. Buffered bypass eliminates the shortcomings associated with true bypass (pops and clicks, and high-end loss when multiple pedals are connected together), as well as signal loss associated with other types of switching circuits. Heavy duty, all metal construction. Operable with 9V alkaline battery (not included) or optional DC power supply (Tech 21 Model #DC2).
