Whirwind Selector AB Switch

Kept in smoke free home. In good condition- has usual marks from Velcro and is missing 2 screws on the back plate. Does not come with an adapter (I ran it on 9v battery). The Selector Active A/B switcher box gives you the ultimate control over your instruments and your gear. You can alternate between channels A and B or select both. Send one guitar to two amps or use it the other way around to select between two guitars into one amp. Whirlwind's patented, state-of-the-art optical switching prevents noise, pops or crackles and no alteration of your tone. Bright LEDs indicate channel status. Plus, it's built tough to handle the rigors of live performance. It runs on one 9V battery or with optional external 9V power supply (T401-ND).
