yep, i'm not a big fan of that "wall of sound" kinda tone, either, but the dual recto got famous mainly due to the nu metal guys using em.
after all, that's why i also mentioned DHIADW as a showcase for the thrashier, tighter side of the dual recto. also, check out recent cannibal corpse to get an idea of what a dual recto (well, technically it's a triple
) sounds like in a death metal context.
mh....what's your tuning? i kinda found that ENGL amps are quite good for the low tuned, gain heavy stop/go "meshuggah" kinda sound (although imho that's pretty much the only thing they do well
).
let's do it the other way round, why dontcha name a few records with your fave guitar sounds, and we try to name a few amps that do these sounds.
in general, for a tight accurate sound, a 5150 is your best bet if you're on a budget. if you got some more cash, you might also want to check out the mesa mark series, mark III and IV come to mind (check out nevermore - politics of ecstacy for a killer example of mark IV tone, or early dream theater). in case money ain't no issue, DEFINITELY check out the framus cobra, too. very low mid voiced amp, and REALLY clear. kinda like a tighter, clearer recto with some marshall thrown in, too.
and of course, you could always go the modded or boosted marshall route, exodus - tempo of the damned comes to mind.
