Switchbone V2

The Switchbone V2 lets a player route one instrument to two or three amplifiers and change between them without audible switching noise. The switching is done with an opto-coupler, and the signal path is fully discrete Class-A. A transformer isolates the outputs to remove buzz, hum and ground-loop noise. A Drag control corrects the load seen by the instrument so the tone stays natural.

Beyond switching, the unit includes a high-powered clean boost that can be engaged for solos. It can be used as a standard ABY splitter, as an ABC selector by using the tuner/out-C output as a third amp feed, or as a channel selector for older two-channel amps. In that last case the Slingshot output can be used to control amp settings such as reverb.

The manufacturer lists the product as discontinued and no longer shipping, and it keeps the user guide and smart sheet available for owners. The part number is R800 7081 00.
