Featuring a true-bypass dual instrument input with a DIM switch on the second channel allowing for volume matching between the two instruments, the Radial BigShot i/O True-Bypass Instrument Selector is an essential rig component built to last for years. Housed in a diehard metal chassis, this switcher is the perfect avenue for fast handoffs between instruments while feeding into the same amp. Whether you're toggling between guitars, basses, synths, or any combination of the three, the BigShot i/O's got the job on lock.
