Description
Running two amps? The Radial BigShot ABY handles the routing without coloring your tone. It’s a fully passive ABY switcher — no buffers, no chips in the path — so what leaves your guitar is exactly what hits your amp(s). Flip it to send your signal to Amp A, Amp B, or both at once for that classic dual-amp wall of sound.
Ground loops are a common headache when running multiple amps, and Radial built the fix right in: an onboard isolation transformer paired with a ground lift switch kills the hum and buzz before it starts. Once your amps are hum-free, use the 180° polarity reverse to flip the second amp’s phase so both cabinets push air together instead of canceling each other out.
A dedicated tuner output taps the signal ahead of the switching stage, so your tuner stays lit and ready without ever touching your tone or getting kicked out of the loop when you switch amps. Plug in 9V power (external supply or pedalboard brick) and bright LEDs give you an instant read on which amp is live — pull the power and the pedal keeps working, since the audio path itself never needs it.
Built into a compact, road-tough enclosure, it tucks into tight pedalboard real estate without hogging space. This unit is sold as open box/demo — fully functional and ready for the road.
