Ok so the past few gigs i had my amp has been acting weird. It would kinda sizzle in and out for a bit and then be fine. It didnt matter what channel i was on it would still do it. I am running a RM4 and a RT2/50. Any ideas on what might be up? It would just do it out of the blue and then be fine for a while.. I just want to get the issue fixed before it totally craps out on me at a gig because i dont currently have a backup amp....
