Radial
JX•2 Switchbone
• AB-Y Class-A switcher
• Noiseless switching between amplifiers
• Class-A circuit for exceptional audio
• Unique Drag™ control load correction
• Built-in Power Boost circuit with mid control
• Transformer isolated to eliminate ground loops
The Switchbone employs the same Class-A circuit as the critically acclaimed
Radial JD7 Injector for exceptional audio performance. Radial's unique
Drag™ control provides single-knob load correction to re-introduce
the natural relationship between the amp and guitar pickup that is invariably
lost when the guitar is buffered or split to drive two amps. To eliminate
hum and buzz caused by ground loops, the Switchbone’s second output
is transformer equipped for 100% isolation.
To further advantage the performer, a variable Power Boost circuit allows
gain boost, mid-boost or a combination to be introduced for soloing.
An innovative ‘toggle-mode™’ foot switch with large,
‘easy to see’ flashing LED indicators makes switching or
combining amps easy without having to tap-dance when changing sounds.
A separate Tuner out is also provided to keep the tuner circuit out
of the audio signal path.
The Radial JX2 Switchbone is easy to use, intuitive and fun!
Now isn’t that what playing guitar is all about?

Switchbone Development
For years, guitarists have been searching for a real solution for ABY
amp switching and combining. One would think that in this day of unbelievable
technology, that building this type of device would be easy. And of
course it is easy…. unless you are intent on retaining the original
sound of the guitar….
For those that have tried connecting two amplifiers together using Y-cords
or some of the other AB-Y boxes that have come before, you are familiar
with the many challenges: Drop in gain, tone changes, buzz and hum just
to name a few. The Radial Switchbone is a remarkable device that deals
with all of these problems and brings forth a design that is easy to
use, musical and truly effective. The Radial Switchbone has been optimized
for stage use and allows a guitar to drive two amplifiers and do it
while retaining the natural sound of the instrument without introducing
buzz, hum, distortion or switching noise.
The Radial Switchbone begins with the concept that most ‘tone
crazy’ players will generally use two amps on stage. When driving
two amplifiers with one guitar, the signal from the pickup is divided
in two and the sound changes. To get around this problem, the Switchbone
employs a unique Class-A amplifier circuit that has been optimized for
use with guitars. With Radial customers like Eric Johnson, Steve Lukather,
Carlos Santana, Steve Stevens and Neal Schon, we are not allowed to
alter the sound of their favorite vintage axe. The sound must be real!

This
leads to the next problem: Your guitar has now gone
from being passive to essentially becoming active. Your pickup is no
longer connected directly to the amplifier. It is being ‘buffered’
(amplified) by the Switchbone. The natural relationship is lost. To
compensate for this, we have introduced a feature called Drag™
control to allow you to reintroduce the natural loading that is lost.
With load-correction, the instrument goes back to normal. It breathes!
Then, as soon as you connect your two amplifiers together they hum,
they buzz and sometimes even spark with hundreds of volts! This is due
to the way that each manufacturer builds their amplifiers. Some use
positive ground, others negative. Some use the chassis as a ground plane
while old designs from the 50’s and 60’s do not even have
proper 3-pin safety U-grounds! To solve these problems, the Radial Switchbone
incorporates a transformer-isolated output, a ground lift switch, and
a polarity reverse switch. This isolates the electrical current flow
of each amplifier and eliminates ground loops.
Of course, once you get these amps connected together, you have to control
them! This is where the Switchbone also shines! The Switchbone is easy
to use. The foot switch layout and LED readout follows a ‘common
sense’ and intuitive approach that is very natural. We have also
added a boost circuit to allow you to ‘step-up’ the output
to both amps simultaneously for a solo or extra saturation when playing
through a distorted sound. For icing on the cake, we added a separate
output for your tuner. This takes the tuner out of the audio circuit,
thus ensuring you get the direct tone of your guitar without extra loading.
