Streamline Your Guitar Rig

If you have a complex live guitar rig, Sweetwater has a device that makes sweet, streamlined order out of chaos. It's the JX-42, from Radial. The touring guitarist's best friend, the JX-42 guitar and amp switcher can simultaneously deal with up to four guitars and two amplifiers. Operation is brilliantly simple. There are four switches; each one immediately turns off the previous channel when it's selected. For visual feedback on darkened stages, there are four easy-to-see corresponding LEDs. Radial uses opto-resistive couplers to ramp the signal up and down, so no popping occurs - a potential hazard with high-gain amps. Investing in the optional JR5 footswitch gives you remote control over the JX-42's input channels.

Radial JX-42 at a Glance:
  • Switching made easy
  • Absolute sonic fidelity
  • Tour-tough Radial build quality
Switching made easy

The Radial JX-42 has two main stage amp outputs, transformer-isolated to eradicate buzz and hum due to ground loops. You can select your amps using the front panel A/B selector switch or with the optional Radial JR2 remote footswitch plugged into the JX-42's JR2 TRS jack. Using the JR2 will also allow you to mute your amps for silent tuning onstage.

Absolute sonic fidelity

Under the bonnet, the JX-42 rocks Radial's acclaimed Class A, 100% discrete buffering circuit for absolute sonic fidelity. Each of the four input channels is fitted with a recessed dual-function potentiometer that you can assign either as a gain control to match wireless systems or as a drag control for exacting load correction when you're using magnetic pickups. The drag control function gives you the feel and tone of being connected straight into your guitar amplifier.

Tour-tough Radial build quality

In typical Radial fashion, the JX-42 is built tour-tough from 15-gauge steel and rocks Radial's trademarked bookend design that creates a safety zone around knobs and switches. The JX-42's rugged I-Beam construction creates rigidity that protects the internally mounted circuit board from torquing, which could result in cold solder joints. You can rackmount one or two JX-42s in a single 19" rack space with optional rack ears.

  • Compact guitar and amp switcher
  • Handles up to 4 guitars and 2 amps simultaneously
  • Ultra-quiet opto-resistive switching
  • Transformer-isolated to eradicate buzz and hum due to ground loops
  • Optional remote-control footswitches

The Radial JX-42 makes your complex guitar rig sing!
