I had owned the nitro... it feel way short of what I expected, so I bought a diamond Phantom. I do own a diezel herbert, thats in a league of its own, sounds nothing like a splawn. The herbert has a more polished high gain roar, tight, compressed with mid cut in on + side. Still, my favorite amp. However, last night a friend of mine came over with his Quickrod, amazing hot rodded marshall tone, RAW n Powerful, nice chunk and definition to it, I tried diff tubes in the nitro, diff settings, diff pickups ( i own many guitars) I play everything thru basson 4x12s, Quickrod guy said the splawn sounded better thru the bassons than his splawn x pattern bb/sb cab.I could not stand the sterile tone of the nitro, it was loud, low end, not enuff bite.
