The JR5 Remote Footswitch from Radial Engineering is designed for use with the JX44 Air Control Guitar Signal Manager. It is a 5-function footswitch which is equipped with an internal memory enabling you to store 4 amp scenes and recall them with a single foot action. A second JR5 can also be used to activate or mute guitars when 2 foot controllers are used together with the JX44. When used with the JX44 on a big stage, amps or effects loops can be remotely controlled, letting you set up various scenes for instant setup changes, and a second JR5 can enable switching between 4 instruments for quick changes between songs.
