User guide

Start with 1(A) by turning your amp volume up. Now do the same by
switching to 2(B). Once both channels are working and are set to
relatively the same volume, depress the BOTH foot switch. Both amps
should now be on.
Now listen to the residual noise. Try
lifting the ground switch on output 2(B).
If you cannot hear a difference, then
leave the ground connected. Now try
reversing the polarity. This will give you
a sense of spacious-ness when out of
phase and a more unified and centered
sound when in phase.
The polarity reverse has been designed
to allow you to connect to two different amplifiers or two amp chan-
nels and compensate for the way these have been wired. It should
be noted that many effect pedals also reverse the polarity as sound
passes through them.
4. SWITCH LED INDICATORS
With the Switchbone, you do not have to tap dance to get your set-ups.
The innovative ‘Toggle mode™’ switch allows you to toggle between
two amps with the touch of a switch. Each amp has an LED indicator
that lets you know what is on.
When the BOTH switch is depressed, the BOTH LED will go on and
the newly activated amplifier LED will begin to flash. The flashing light
tells you that when the BOTH is disengaged, this amp output will turn
off. The cool thing about this feature is that when both amps are on,
you can hit the TOGGLE switch and the flashing LED will toggle from
Amp-1 to Amp-2. This means that you can pre-determine which amp
will be turned off by simply depressing the
TOGGLE switch so that the amp that you
intend to shut off is in the flashing mode.
No tap dancing!

Example:
When amp 1 is on, the channel 1 LED
next to the TOGGLE switch will be lit.
Depress the BOTH switch and the 2nd
channel is now activated. The new chan-
nel LED will flash.
Hit the TOGGLE foot switch and the
flashing LED will toggle between the two
channels.
To go back to single channel operation,
depress the BOTH switch again and the
flashing channel will go off.
