RADIAL BIGSHOT ABY.
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.
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
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
- 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
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
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.
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.
