Ugh, I bought a fuzz pedal a long time ago. The demos were great; it had an incredible reputation. Small builder so I had to get on a list and it was at the upper end of my price range. Finally the day arrived and it sucked! Sucked, sucked, sucked. I was crestfallen. Took me a whole day to realize the wah was on.I've never had an issue.. especially if its a fuzz. The only time I can think of is if when I set up my rig and the wah is on and I can't figure out why my rig sounds weird.. "oh the wah is already on!"
