sounds like a killer setup !Hey! Well, I put the '62 Bugle boy in V1, the '59 Mullard in V2, and the '65 Mullard in V3. I tried many different permutations and this one sounded REALLY good. Oddly, the 60's GE long plate was really good in V1, as well. Surprisingly so. It's stiff competition for the Bugle Boy.
and I totally agree - there are always alternatives, like your GE.
over here, I try lots of things with every amp.
eventually things will settle down, and then I leave this amp alone and simply enjoy playing it ...
took me a few years, but by now almost all of my amps have "reached nirvana" (not the band !), 90% select old glass, a few LPS or 6N4 inbetween, and I don't regret anything !
have fun !
