Designed for the purist, the Radial BigShot ABY is an ultra compact, 100% passive foot switch that provides true bypass ABY amp switching capabilities with A or B toggle and A + B combine functionality. This assures the guitar signal is routed directly to the amp without any buffering, loading or tone altering circuits.

To add versatility, the BigShot ABY has a built-in transformer that can be engaged to eliminate troublesome ground loops. Once on, you can also ensure your two amps are properly in phase using the 180º polarity reverse switch.

The compact yet ultra rugged design makes the BigShot ABY ideal for pedalboard designs where space is always at a premium. Furthermore, because it does not require powering to make it work, it eliminates the need for batteries and space hungry power supplies.

- True bypass ABY amp selector with tuner out
- On-board transformer to eliminate ground buzz
- 180° polarity reverse to phase-match amps
- Compact and rugged for pedalboards
- Plug and play easy to use

Radial opted to make the BigShot ABY completely passive so that no powering would be required. This trade off eliminates the use of lights and need for batteries or power supply. Instead, we added two functions that are not found on any other low cost AB-Y switchers: transformer isolation and 180º polarity reverse.

When combining two amps together, often times, noise caused by ground loops can enter the signal path. The buzz and hum can often be so loud that it makes playing impossible. For these instances, the BigShot is equipped with an isolation transformer that can be switched in. Transformers are wonderful devices that allow the audio signal to pass while eliminating hum and buzz caused by ground loops. Once engaged, the transformer also lets you set both amps ‘in phase’ a feature that once again is unique to the BigShot.

Keep in mind that the trade off here is tone. When you engage the transformer, even though you are still passive, you are no longer technically ‘true bypass’. This means that the tone going through the transformer will be affected unless you place a buffer in front of it. Many pedals incorporate buffers into the signal path. This can be good or bad, depending on the quality of the buffer. The Radial BigShot PB1 combination power booster / buffer is one of the best buffers on the market. With a buffer in front of the BigShot ABY, you can drive your tuner without noise and run longer cables.

The cool thing here is that BigShots are designed to accommodate both camps: true-bypass and buffered to give you the freedom to choose as your needs progress.
