Hmm, so I don't think I'd want a JMP or early 800, cuz I'd rather not have to get the thing roaring to get a useable tone out of it (and as such, there's no fucking way I'd get a 2203! Gotta go the 2204 route it would seem) - I can't deny, from your very helpful description, Exocaster, the 2205 sounds the most appealing, cuz even if there's a bit of a sacrifice in tone (and I'd imagine it's negligible), having an FX loop is pretty mandatory, and that built in boost/TS circuit and the fact that it's easier to coax high-gain out of it; well, it seems like the best choice for an amp that I wouldn't necessarily want to be a studio-only number (cuz I can't afford those luxuries these days!)
So what do you guys think? Is a 2204 800 really worth all the sacrifices in features over a 2205?
first off, the actual volume difference between the 50 and 100w models is pretty much negligible...there IS however a noticable difference in body and fullness of the tone, with the 100w being the fuller sounding one, since the output section is just...well...bigger
don't know the technical details
sure, the 50w is somewhat easier to get into poweramp saturation, but it'll still be damned loud, that's for sure.
what i'm trying to say is, whether you go for the 50 or 100w version, they both will be LOUD, but the 100w might sound a tad heavier.
as for the single vs split channel versions, well, i haven't played a single channel, but i own a 2210, and it's a great sounding head. the clean is actually usable with a nice midrangey twang, but it's not exactly loud, nor is it fender clean...duh. the boost channel rocks, though. while there are no super brootalz heavy tones to be found in there, it has enough gain for pretty much every form of metal short of total death annihilation. i used to play thrash metal going straight in with the gains around 8/10 or so. i haven't used the fx loop, so i can't comment on that. same goes for the DI out. the reverb is ok sounding...nothing out of the ordinary, but not bad either.
and as i said above, it's LOUD. and cuts through like mad. i remember shows where i was running a 212 cab as opposed to the other guitar player running a 412, and i still could hear me all over the stage. and i wasn't even playing *that* loud.
the best part of the 2210 definitely is its lead tone...it has a very nice singing quality.
