Odd question here. I have a Peavey Nitrobass head. Can you just take all of the innards out and slap it into a rack case? I'm looking at getting a tuner and preamp and instead of carting the head, rack case with tuner/pre amp etc in it I'd like one complete package. Buy a rackmount power amp you say? Monetary constraints on that now as I'd like at least like to have a decent pre amp first as well as getting myself a 5 banger before looking at that since the head/cab I use now was a gift from friend. Free gear=best sound for the buck possible.
