CONGRATULATIONS on your purchase of the Radial BigShot ABY. The Radial BigShot ABY
is a foot-controllable device that allows you to toggle your guitar signal between two ampliers
or have them both play at the same time. The ABY’s circuit is completely passive to ensure
100% true bypass performance. When powered with an external 9VDC power supply, bright
and easy to see LEDs deliver on stage switching cues so you know exactly what your amp
status is at all times.
To add greater versatility, the BigShot ABY incorporates an audio transformer that may be
inserted into the signal path between the guitar and OUTPUT-B. This is used along with the
ground lift switch to help eliminate buzz and hum caused by ground loops, a common occur-
rence when connecting two amps together. A 180º polarity reverse switch can also be engaged
that lets you play both amps in phase. Finally, a third output that is always on is provided for
an electronic tuner. Although primarily intended for guitars, the Radial BigShot ABY may be
used for all types of instruments in applications where you want to feed two ampliers from a
single source.
CONNECTING AND TESTING
To power the LEDs, the BigShot ABY requires an external Boss style power adapter that out-
puts 9VDC center pin negative. It is recommended to begin testing the system without a tuner
connected. Add the tuner to the setup when you are sure the BigShot ABY and both ampliers
are working properly. Before connecting the BigShot ABY, make sure your ampliers are
unplugged from AC power, turned off and the volume controls turned all the way down.
1. Begin by connecting the 1/4” guitar cables. Connect your guitar to the BigShot’s INPUT.
Connect the BigShot’s OUTPUT-A to your main amplier and OUTPUT-B to your second
amp.

2. At this point it is important to read the caution statement on the back cover and en-
sure all your equipment is properly grounded. If your equipment meets all electrical safety
requirements, you may connect the ampliers to an AC power outlet.
3. Turn the amps on and begin testing at a low volume level. Conrm that both amps are
working with the A - B toggle footswitch. Try depressing the BigShot’s BOTH switch to test
for ground loop hum. If you encounter a loud hum or buzz, rst try lifting the ground by slid-
ing the LIFT switch to the upper position ( ). If the noise persists, try engaging the isolation
transformer by sliding the ISO switch to the upper position ( ). If possible, test the system
with more than one guitar. With some pickups, engaging the ISO switch can cause a change
in the sound. See the section “USING THE BIGSHOT ABY” further on in this manual for more
information. If all sounds OK, you are now set to check the phase between amps.
4. Once both amps are working it’s very important to ensure your amps are phase aligned and
the loudspeakers are moving in the same direction. Amplier OUTPUT-B is equipped with a
180º polarity reverse switch to help you with this task. This function only works when the ISO
switch is set to the upward position ( ). Set the ampliers to an equal volume and depress the
BOTH switch so both amps are on. It also helps to have the amps side by side. Play through
the amps with the 180º switch in the lower position ( ). Then play with the switch in the upper
position ( ). One position of the 180º switch will sound fuller, with better bass response indi-
cating proper phase between amps. The other position will sound hollow and weak, indicating
the amps are out of phase. Use the setting that sounds best.
