The Radial BigShot ABY is a compact ABY switcher that enables you to either switch between two amplifiers or combine the signal when you want both amps to play at the same time.
Radial BigShot ABY Features
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
Designed for the purist, this true-bypass ABY switcher is completely passive meaning that there are no tone altering buffers in between the guitar and the amplifier. With the BigShot ABY, you get the pure tone from your guitar plugged direct into your amp! To add versatility, the BigShot ABY is also equipped with a separate tuner out. This 'always on' output feeds your tuner for constant monitoring while keeping it out of the signal chain. Should you experience hum and buzz problems due to ground loops, the BigShot ABY comes to the rescue with a built-in isolation transformer and ground lift switch. Once engaged, you can toggle the polarity of the second amplifier to ensure both amps play in absolute phase.
In use, the BigShot ABY is both simple to use and efficient on stage. When powered by an external 9V supply or pedalboard power brick, full size super-bright LEDs spring to life to provide instant on-stage amplifier status readout. When power is unavailable, the passive audio signal path still works, unaffected. The compact yet ultra-rugged design makes the BigShot ABY ideal for pedalboards where space is always at a premium.
The BigShot ABY... the most versatile true-bypass switcher made today!
I purchased the Radial pedal to eliminate a grounding loop in my rig because I am using two amps and the hum noise was pronounced.
I love the variations you can select, even a phase switch to make sure both amps are producing the loudest and best sound possible. The outcome is very workable and much...

Well Built, does what it's supposed to do!
Very sturdy and well built, and very quiet. Simple to set up too. I use it to split my signal so I can add my PC based guitar synth to my signal for certain parts of songs etc. Only minor drawback is it is a bit heavy. Highly recommend this if you are looking for an ABY for dual amps etc.

Switch between amps easily
This pedal quietly switches between my two amps. It can also be used to run two guitars into the same amp and switch between them. I've had no issues with noise or grounding. I'm very pleased with this piece of equipment.
