Now that I finally have my music room failry done I've been playing my amps again. And....they're buzzing like mosquito's. At first I thought it might may confined to something I did wrong on my Metro 45 build but everything is buzzing. I bought one of those AC line check plugs (with the 3 lights that tell you polarity, ground, phase, etc ) and I did find a couple of things to fix this weekend. And I did make the rookie mistake of using a couple of dimmers in the room

What else should I look for? It's way bad.
