If you want that unique Dime tone, you can take any amp on the planet, max the gain/treble/presence and then roll off every scrap of mids and lows. Voila! :lol:
I'll take Dave's tone over Dime's ten out of ten times.
I can't say I'm intimiately familar with his current tone, but back in the day he was almost certainly unique because he was broke. Dave just wanted to outdo his old band, and IMO, he did. Recent 'Death albums don't do much for me but they're certainly a zillion times better than Lulo, Load, and every other shitpile Metallica has released since AJFA.
