Radial Engineering's BigShot I/O switching pedal makes switching between two different instruments easy and reliable. The pedal's two switches allow you to select between two instruments on the fly or mute your entire signal. The BigShot I/O's onboard Trim and variable level for Input-2 ensure the level of your instruments can be exactly matched or dialed to taste. Flip the Tuner Out switch, and you'll enjoy constant monitoring of your tuning without affecting your signal. And the BigShot I/O is very popular for its passive, true-bypass design.
