Ah Charley,
You're growing up! LOL! When young, I think we all think bigger is better: nothing's more impressive than a huge guitar rig, right? Then we get older, and the back and knees start to hurt and we get tired of lugging all that crap around. When we come to our senses, portable and simple wins out over the Marshall Stack syndrome.
Enjoy your new guitar and rig (and welcome to the club)!
Cheers,
Kevin
PS, Assuming you don't already have a buyer, and that you've already considered EBAY, you might also wanna try the Two-Rock website's owners forum...after they berate you for daring to sell your amp, they'll probably give you top dollar for it, LOL!
