I’m having the same issue. When I select a preset it activates and sounds as it should. when I turn off the “Active” button the effect turns off as it should but when I press the “Active” button again I get an almost inaudible amount of sound. I can just barely hear any output. I can tell that the effect is “on” but the volume is so low that it is effectively muted. If I change presets then the volume is back to normal. It does this regardless of what preset I change from/to and happens if its activated on the effect pedal, through midi, or through the app. Any ideas?
