I recently modded my MP1 to the Mod4 MKII also did the MDRT upgrade. While doing this I noticed I still have the original tubes in it. After the upgrades were done I could really notice how tired and lack luster the old tubes were. I currently have the following new tubes:
3 Mesa boogie 12ax7a Russian 2 white label's
1 Mesa boogie 12ax7a black label
1 Ruby 12ax7a
1 GT 12ax7r
I also have 2 slightly used Tung Sol reissues in my MT200 which I currently am not using.
From the info I could find the Ruby and GT are lower gain, the black label mesa is a medium gain and the white label mesa russian2 are a med/high gain. Anyone have an idea of a good combo of what would work best in V1 and V2 with this mod? Trying to nail that modded George Lynch type tone. I was thinking Ruby in V1 and a russian2 in V2, but I don't want to spend the day tube rolling.
