I was playing last weekend at a gig, and had 8 banks of presets sets. It worked fine at my house, then when i arrived to the venue, parameters started changing on their own. I have heard that the knobs do this if they are dirty but my timefactor is clean. I wanted to know what i can do to fix this, and if this is a common problem?
Just for example i would have a preset selected, and the delay filter and speeds would change.
