I got a non-functioning Princeton Chorus w 2x10's for 50 bucks with the notion of gutting it. The inner dimensions is 20 3/4 so neither a Regualr Princeton chassis or say a Deluxe Reverb chassis will fit. I have a buddy in Colorado who is a welder who I could get to plasma cut a chassis down for me, but he's about to have open-heart surgery. The chassis that it came with is fairly useless. Any suggestions would be greatly appreciated!
