Radial BigShot ABY True Bypass Guitar Amp Switcher / Selector
Guaranteed Safe Checkout:
The Radial BigShot ABY is a compact true-bypass ABY switcher built to let you run two amplifiers on stage, whether that's switching between them or driving both at once, without adding noise or colouring your tone. An on-board isolation transformer and ground lift deal with buzz and hum from ground loops, while a 180° polarity reverse switch keeps both amps in phase so frequencies don't cancel out. The two latching footswitches control amp selection, and the pedal doubles as a simple mute switch for quiet on-stage tuning via its separate tuner output.
Highlights

- 180 degree polarity reverse switch keeps both amps in phase to avoid frequency cancellation
- Dedicated tuner output keeps the tuning circuit out of the main signal path
