Compact guitar and amp switcher made to handle up to four guitars and two amps.

The Radial JX42 V2 is a four-instrument, two-amp switching device designed to streamline any stage setup to ensure professional changeovers and zero downtime should problems arise. Four instrument inputs are provided on both the front and rear panels, with large toggle switches and bright LED indicators for immediate visual feedback. Multiple instruments can be active simultaneously to prevent cutting off the performance when handing off a live guitar, and all inactive instruments feed an always-on tuner output for silent tune-ups at a moment’s notice. Dual amplifier outputs are available to switch between stage amps at will or as a redundancy in case of failure during a performance. The front panel controls can also be accessed using the optional JR-5 and JR-2 remotes, or MIDI controllers can be used to activate all features of the JX42 V2.


  • Select between 4 guitars and 2 amps
  • Individual input trims and Drag Control load correction
  • Remote footswitch control with optional JR-2 and JR-5 switches
