User guide

The Radial Switchbone comes equipped with a 15VDC power supply.

Connect this to your pedal and then to the AC power outlet. Before

connecting your guitar and ampliﬁers, make sure the ampliﬁers are

turned off. The Switchbone will automatically turn on as soon as it is

connected to power. Before you start, make sure that the BOOST light

is off (boost turned off) and the BOTH switch/LED is also off. The only

LED that should be on is either 1(A) or 2(B) output above the toggle

select.

CAUTION: Make sure you have read the electrical connections and

tested your amps for proper grounding as detailed previously.

To reduce opportunity for shock hazard or damage to the JX2 or

connected equipment, plug the ¼” connectors into the ampliﬁers ﬁrst

and then to the JX2. This is especially important when using old

ampliﬁers that do not have 3-prong plugs as the possibility exists to

touch the chassis ground with the connector plug tip when the plug is

inserted into the jack.

Connecting your ampliﬁers is easy. Output 1(A) should be for your

main ampliﬁer. Output 2(B) will be the alternate. The 2(B) output in-

corporates the isolation transformer, ground lift switch and 180 degree

polarity reverse. Output 1(A) is the ground channel and should con-

nect to an ampliﬁer that is equipped with a proper U safety ground.

You can insert effect pedals before or after the JX2 Switchbone to

create all kinds of pedal set-ups. This is discussed in ‘Set-ups’ later

in this manual.

Once your set-up is connected, make sure your amp volumes and ef-

fect pedals are OFF before you turn on your amps. The following tests

should be done with both amps set on a clean setting so that you can

hear any potential noise, phase and hum problems.
