Radial Big Shot I/O Switcher... The Original. The only differences between the original (legacy version) and new BigShot i/o are aesthetics and the addition of the LEDs for visual feedback. You can operate the new BigShot i/o with or without a 9V Boss-Style adapter, the power is only used to illuminate the LEDs. Great for pro stage hands free control of your rig! The Radial BigShot i/o is an easy to use instrument selector that lets you quickly transition between any two instruments and send the output signal to your amp. Because the i/o is 100% true-bypass, it addresses the needs of the most demanding purist. Super compact, extremely rugged and 100% passive, the BigShot i/o does not require any powering to make it work. This makes it ideal for pedalboards where the use of batteries or power supplies is painful! • MFSKU R800 7212 00 • UPC 676101036295
