Ah, I do recall reading something about that. All the more reason to design what I'm suggesting into the product from the start! Honestly, i'd be happy with an integrated handle, knob protection, and some sort of skeleton rubber edge bump guard... So I don't need a bag or rack.Agedhorse once posted that the metal case is an integral part of the thermal/cooling system.
I left some "air space" between the amp and my case.
