I have a Line 6 M9 that is acting strange. I'm using an external 'preset' box instead of an expression pedal. The preset box is simply a latching switch with a 10k resistor. I can set min/max settings on an effect and use the preset box to toggle between the two settings. What's weird is that I can do it a half dozen times without a problem, then all of a sudden it'll stop working and forget the min/mix settings and I have to set them again to get it to work. Any ideas on what's going wrong here?
