This is near the exact tone that I'm always trying to get out of my UL, though it can get really close, it's still missing something
I might cut a little somewhere in the 400-800hz range, for my taste, but I'm sure that there's already plenty of post work done. Do any of the cheaper Marks sound like this? I remember hearing that the Mesa Studio Preamp was based on this amp. That would probably sound awesome running through the UL's KT88 power section. The Mark iv has always been on my list, but not really that high up. Bah, the differences between this and my amp are so subtle that it's not worth contemplating, but I can't help it

Should I add this to my amps to buy list? Which

if you're wondering, is currently:
1. Randall Satan(at least #1 to try, who knows after that)
2. VHT Deliverence
3. Rhodes Colossus
4. Kaos Hatred
5. Mesa Mark IV
6 through 9999999 of the list contains every other amp known to man
