My current favorite is the Diezel Herbert. I love it and not just for high gain. Channel 2 (both + and -) absolutely kills. Cleans are stunning. More gain than I'll ever use or need. Silky smooth lead tones. I mostly play metal, but not the tuned to B, cookie monster vocals stuff. Think a mix between the modern metal and 80s Iron Maidenish stuff. Harmony, melody, and a singer who can carry a tune.
That being said, I love my Mesa Mark III. It can get me just about any tone I want. I've played in Dead bands, Alt Rock bands, Prog rock bands, cover bands, you name it. The Mark III has carried me through all that with flying colors and I still use it at times instead of the Herbert.
And last but not least, just plugging my Les Paul into my old Fender Super sounds heavenly. I've gigged that amp with just TS9 and my Les Paul and been very happy. It's a one trick pony, but it's a damn good trick.
I wouldn't want to part with any of these. I've had Peaveys (I think every bandit every made), Mesa Nomads, carvin (X60,
SX200) and a few others I'm probably forgetting. None of them were worth keeping to me. The 3 I have now I can't imagine parting with. Though the Herbert is my current favorite, it's nice to have options to fit my moods.
