The Radial BigShit i/o instrument selector is designed to let you transition quickly and easily between two instruments. Because of the 100% true-bypass circuit, it addresses the needs of the most demanding purist by providiing a direct signal path to the amp. A level control on input-B lets you balance the relative volume of the two instruments before the amplifier and a unique 'bright' switch lets you compensate for high frequency loss due to longer cables. The i/o's mute' footwwitch turns the signal to the amp off and diverts it to the tuner output for quit on-stage adjustments. Compact and extremely rugged, the BigShot i/o does not require any power and is super easy to integrate into any pedalboard setup.
