Well, the new preamp valves are now in but as it's very late I won't get the chance to test them until after work tomorrow. Unfortunately, I don't expect the big difference I'd hoped for as the valves that were in there weren't cheap Chinese valves but JJ valves. Still, we'll see.
That changes things of course, but even though it wonīt be the expected change there should be a noticable one. Plus you now have more options for switching things around. TAD V1 with a JJ V2 or vice versa. I am staying positive here.
Inspired by this thread I also changed around the preamp in my TT, now having a Tube Town AX7 V1 and a Sylvania AT7 V2. Man, this transformed the end. Took out a good bit of gain, but improved it too. It now feels much more open, touch sensitive, defined, sweet, and it reacts better to guitar controlls. I have not yet tried it for metal, but for hard rock, classic metal, and blues especially this feels amazing. The singing lead sounds now...oh my.
Not the last experiment for now though. I still got other tubes, from AX7 to AU7.
