I was just wondering if, I were to use my Mesa Boogie 400+ sitting sideways in a rack would it screw it up? I mean screw it up at all long term, short term, is it working harder sideways, or anything. Is there any benefit to having it sitting flat? I stow it sideways when it's not in use, should I not do that? It's built like a brick crap house, so I am just about sure that everything's fine with it sideways. someone just planted a seed in my head like, "Oh, you keep your amp sideways?", but when I said "Yeah" dude was like a fricking cricket. Put my mind 100% at ease guys and let me know, so I can sleep at night.
