Yamaha uses a floating ground system, which can cause problems if you are using two foot pedals that have a grounded, metal frame and touch each other. This has been a problem for many years and was never addressed. Boss pedals, the type that locked together, were notorious for this problem.
Good Luck,

Gary, I was a Boss dealer for many years..and never heard of this problem..I would think that Bill's problem was a ground fault problem with him being the activist...
