I use an original Model T, in the band 3 GUYS THAT HATE YOU
I use it along side a Red Bear half stack, which I have two of, but only use the one right now.
I also have a sec. gen. Model T, but do not use it at the moment due to that fact that we have no van, and no way to take four half stacks to a show. When we get a van I'll be using the two Model T's and the two red bear half stacks together!!!!!
