Radial BigShot ABY True-Bypass Switch Pedal

The never ending quest for great guitar tone drives the purest to extremes. One amp for clean one amp for distortion. But combining amps is not always simple. Often, when two amps are connected together, differing ground references can cause slight buzz to extreme noise that can be so bad that they are unusable. Products such as the popular Radial Switchbone AB-Y switcher provide elegant solutions by introducing a buffer into the signal path and the use of photocell switching, but alas, they do so at a premium price. For many, these extras are not needed.

Another consideration in a switcher pedal is size and practicality in actual use on a pedalboard. The ABY is designed to be as small as possible and with the connectors and cables located at the front of the unit, where they will have the least impact on valuable stage space used. The Radial BigShot ABY answers the need for a compact, simple and effective amp switcher with straight wire true-bypass connectivity for the purist, with the option to switch a noise eliminating transformer into the circuit should ground loop induced hum and buzz be a problem.

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 play back 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 true-bypass device, without any tone-altering buffers between the guitar and the amplifier to ensure you retain the pure tone of your instrument.
