The Xenagama is a three-channel loop switcher equipped with four DC outputs. Its perfect for smaller pedal boards that dont have the room to accommodate a switcher and a power supply. The loops are all true bypass and it also has a separate tuner output. Perfect for pedals or tuners that seem to sucking out your tone while not in use. Takes a standard 9V power supply and can be used passively if so desired, however power outputs will not be active. This small loop switcher is perfect for the minimalist who needs a little more.
