Radial JX42 Guitar Selector w/ 4 Inputs

4x2 Guitar and Amp Switcher

The JX-42™ is a compact guitar and amp switcher made to handle up to four guitars and two amps, with the ability to select inputs and outputs locally or via remote footswitch control.

Compact switching solution
The JX-42 is a surprisingly powerful guitar and amp control center, small enough to fit on top of your amp, but able to switch between up to four guitars and two amplifiers without noise. Each input is equipped with a trim control to level-match input signals, or a Drag control load correction circuit to optimize the impedance presented to magnetic pickups for a more natural tone. Optional JR-5 and JR-2 footswitches can be connected for instant switching available right at your feet, allowing the JX-42 to be rack mounted off-stage when used with wireless systems.

JX-42 Applications

Four guitars – 2 amps
The JX-42 makes it easy to switch between four guitars using the radio-style selector switches. Connect two amps and use the JX2 footswitch to remotely switch between them.

Four basses and DI box
Instantly switch between four basses using the JR5 remote control. For the upright, add a direct box on output B to automatically mute the stage amp when selected.

Adding wireless systems
Use the Trim controls to match the levels from your wireless to your wired guitars. The guitar tech can select guitars using the JR5 remote while the artist selects amps using the JR2.
