-Discontinued-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.
