Radial BigShot ABY

True-Bypass Amp Switcher

Description

The BigShot ABY™ is a compact true-bypass ABY switcher that enables you to switch between two amplifiers or play through both amps at the same time, while eliminating buzz and hum from ground loops.

  • True-bypass ABY amp selector with LED indicators
  • On-board transformer to eliminate hum & buzz
  • 180° polarity reverse to phase-match amps
  • 100% passive audio path, does not require power

Effective control for your two-amp setup

The BigShot ABY makes it easy to run two amps on stage, without introducing noise or altering your tone. The pedal has two latching footswitches that allow you to choose which amp is active, or run through both simultaneously. The second amp output features a ground lift and an isolation transformer that can be engaged to eliminate buzz and hum from ground loops, while a 180° polarity reverse switch ensures both amps playback in phase to avoid frequency cancellation. When powered by an external 9V supply or pedalboard power brick, LEDs provide instant on-stage visual feedback – when power is unavailable, the passive audio circuit still works unaffected. Best of all, the BigShot ABY is a true-bypass device, without any tone-altering buffers between the guitar and the amplifier to ensure you retain the pure tone of your instrument.
