Clumsy me, while stomping I sometimes hit the model select button, with tragic/comical results. Can really mess me up at a gig. Have to find a little cap, like one to a toothpaste tube maybe, that would fit over the model select button, so this can be prevented. Would have to find just the right size, glue a strip of rubber inside so it stays, has to be snug but not so snug that it will press the button when I put it on... it's a whole thing.
Has this ever happened to you?
