True to the Music 1. INTRODUCTION The Radial JX2 Switchbone was born from the demand we received from users like you. The Switchbone is in fact a pared down version of the popular Radial JD7 Injector, a studio recording device that allows as many as 7 amplifiers to be driven from one guitar. The Switchbone has been optimized for stage use and allows a guitar to drive two amplifiers and a tuner from one guitar input and do it without introducing buzz, hum, or distortion. Sounds easy enough… but it is not.
True to the Music 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. We have even added a separate output for your tuner.

True to the Music 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.
True to the Music 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.
True to the Music 5. DRAG™ CONTROL Drag™ control was originally introduced on the Radial JD7 Injector as a means to correct the loading that is lost when a guitar signal passes through an ‘amplification stage’ or a buffer. Here’s the scoop: When you connect your guitar directly to your amp, the amplifier’s input impedance reacts with the pick-up and this relationship plays a critical role in the tone of the instrument and amplifier combination.
True to the Music 7. SET-UPS The Radial Switchbone has been designed for maximum flexibility on pedal boards or as a stand alone amplifier switcher / controller. As such, the Switchbone can be positioned at the input of the signal chain, the output or in between. Where you use the Switchbone is entirely based on how you intend to use it.
True to the Music SWITCHBONE QUESTIONS & ANSWERS Can I use any two amplifiers with the Switchbone? Yes….the Switchbone should be able to be used with any two guitar amplifiers without problems. Make sure you follow the set-up procedures to ensure your equipment is safe. If you are not sure consult a qualified technician. What happens when I reverse the polarity of the 2nd amp? The polarity reverse allows you to correctly line-up the polarity of the devices that you are using.
