Ok, so the tubes have about 25-30 hours on them now (I use a different amp in the house). The EQ settings were quite wavy at first to get my ears happy, with a big drop in settings around the 2 - 4 k mark. I noticed lately the EQ has gotten flatter and flatter as the tubes darken and I tweak. I think I will pull the EQ again and see.

Man, guitar is the best thing ever for people that need to be doing stuff all the time! :)
