Hmm I wouldn't get a RV100, I'd either go with a RV50 combo or a TV50 head if you were set on Oranges. I owned a Thunderverb 200 and it was seriously amazing, blew the rockerverbs out of the water for tone, not tried the 50W though.
But since you mentioned it.. GET THE MATAMP GT1!!!!
Just go get one.. if you don't like it, email me and I'll take it off your hands quickly for you! I wat one of those sooooo bad.
