    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.

    BigShot I/O - Applications

    Using the i/o with two electric guitars
    Switching between a Strat and a Les Paul is easy! Plug the two guitars into the i/o and hit the toggle switch to select. Connect your tuner for quiet onstage tuning using the mute footswitch (see fig 3 above)

    Using the i/o with passive and active bass
    Output levels can vary dramatically between an active bass and a passive one. Connect your traditional fender to input-1 and your active bass to input-2. Turn on the DIM control and reduce the level on input-2 to compensate.

    Switching between acoustic and electric guitars
    Multi instrumentalists are often forced to switch between electric and acoustic guitars. The BigShot i/o makes it easy! Use input-1 for the electric and lower the sensitivity on input-2 for your acoustic to balance the signals.
