Offer Details

The Radial BigShot ABY is a passive, true-bypass signal router designed to switch between two amplifiers or drive both simultaneously without compromising your guitar's tone. Built for reliable stage use, it provides practical solutions to the common issues encountered in dual-amp setups, including ground loops, phase cancellation, and unwanted noise.
Two latching footswitches allow instant selection between amplifier A, amplifier B, or both outputs together. An integrated isolation transformer and ground lift switch help eliminate hum and buzz caused by ground loops, while a 180° polarity reverse switch ensures both amplifiers remain in phase for a full, balanced sound.
The BigShot ABY can also be used as a silent tuning mute when paired with a tuner, or as a simple channel selector for vintage amplifiers with multiple inputs. Its passive audio path operates without power, while an optional 9V supply powers the onboard LEDs for clear visual indication during performance.
