I can tell you right now that the dual recto is gonna win this one.
Anywho..
as far as the later generations go I actually prefer the single.
Contrary to popular belief, the single is practicaly as loud as its larger brothers.
EDIT: If any you post that you like the DR better because "its louder"
please kick yourself in the nuts for me and stop making statements about amplifiers in a public setting :evil:
Sure the others have more headroom, but since I play high gain stuff 99% of the time, I dont need headroom on my dirty channel. To me headroom comes more in handy for clean sounds. Tonewise, the singles definitely win for cleans.
My biggest gripe with current generation dual and tri rectos is the extra channel. I dont need one, but its not like Im exactly against it. IMO its the extra PCB involved that has made these models loose a lil bit of the mojo the older ones had.
