The Radial BigShot i/o is an easy to use instrument selector switch that lets you quickly transition between any two instruments and drive the signal to your amp. Because the i/o is 100% true-bypass, it addresses the needs of the most demanding purist. To further enhance connectivity, input-B is equipped with a level control called DIM that lets you reduce the signal from the louder of your two instruments so that both instruments are matched to the same volume level when they reach the amplifier. When passive instruments are used, a unique bright switch lets you compensate for high frequency loss due to longer cables. To enhance on-stage functionality, the BigShot i/o is equipped with a tuner output. With a simple foot stomp on the MUTE switch, the sound going to the amp is turned off and diverted to the tuner for quiet on-stage adjustments. An always on switch also permits on-the-fly quiet tuning should you wish to have the tuner on at all times. Compact, extremely rugged and completely 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! The BigShot i/o is also perfect for all you instruments and hi-Z line-level signal switching.
