Your power conditioner has gone wonky. Replace it with a new one, and all will be joy. I betcha.
Edited, because I thought about it for a few moments: Perhaps in the mythical land of Canada, you're not forced to play out at the same crappy bars we do here in the States, therefore you may not own a power conditioner. In which case, buy one. Any brand is fine, as long as it's a Furman.

I mean, no offense, but I don't really see why, like guitar players from Creed, or something like that, are on the cover of guitar magazines. Almost anybody can sit down and learn to play those songs.
