My Minimax v.1 has been intermittently distorting and losing volume for just a second or 2, here and there over the last 3 gigs with it. Sounds almost like a blown speaker, but my speakers work flawlessly with any of my other amps, and like I said, the problem is intermittent (unlike a blown speaker). I switched to my backup amp during soundcheck at my last gig because it was doing it pretty bad as soon as I turned it on. I've gotten about 6 years of pretty heavy gigging out of it, but I'm hoping it's not "curtains" for it just yet. I opened it up yesterday and checked all the connections and blew out the dust inside with compressed air (which there was a little bit in there). Since then, I have not been able to re-create the issue at home even after an hour playing on it at various settings and volumes. I'm hoping it's ok now, but I'm not too confident that it won't happen again on stage since the issue started out very sparse and got more frequent over the course of 2 weeks.
I'm thinking maybe it was just dust in the pots? It wasn't crazy dusty in there or anything though. Any thoughts or similar experiences? I'm hoping this isn't the first sign of it dying. Not that it's too expensive to replace, but still, $400 bucks is $400 bucks.
