I have found this forum to be a treasure and a great place to hang out. Plenty of knowledgeable experienced amp builders, with plenty of opinions,
and a ton of solid advice toward building great amps. Speaking of opinions, having now built a couple Rockets, as well as two ODS type amps, the Rocket is a great amp. It seems to play well through different types of speakers and can play clean to mean pretty well, with its clean tones being fantastic (in my opinion). The two keys i found were good power tubes and an OT with 4K primary, which helps keep it clean, as it tends to overdrive fairly easily.
