Right-hand knob stopped working? It's the long-press function

If the right-hand knob on your Expanse seems dead, you've most likely got the long-press function enabled. That function is normally used with the shimmer effects to switch between shimmer and reverb-only — you do it by turning the right-hand knob (shimmer level) down to 0. If it's still enabled while a different effect is loaded, it'll look like the right-hand knob does nothing. Worth knowing: the long-press function (like tap tempo) doesn't clear itself when you load a new effect. You have to disable it on the pedal: 1. Remove power from the pedal. 2. Hold the footswitch down, and reapply power while keeping it held. 3. If you're using the ExP Controller, switch to the effect slot you want to configure. 4. Turn the right-hand knob fully counter-clockwise. 5. Release the footswitch. The long-press function is now disabled.
