We tried each amp in every configuration/channel cloning. We both preferred red/modern boosted with an 808 on each amp. Orange and Orange cloned to Modern or Modern with Orange cloned to Modern didn't do it for either of us—but I can see why people like those. Both Triples (Rev G and Reissue) sounded awful.
I took a look inside all the amps and didn't notice any mods other than the all black G had a bias mod. Ted also replaced the Red channel's gain pot with 1M/4700pF and it's running KT66s now. But I played the amp before that was done and after.
