Man, I've gotta try those fancy brands you all mention. Cuz I got such dramatic tone mods from swapping tubes just with the junkers I have.
I had a box of over twenty old tubes and played around trying them in V2 and then in V1 positions. The baseline tone was fun, but it has that characteristic clippy raspy sound. And, as I would bend a double stop, there was a small unappealing high beating overtone. I settled on a tube in V1 that was everything I was looking for. I moved the original Marshall red label V1 into V2 just cuz it looks premium. The best V1 tube in my hodge podge was labeled MESA 12AX7-A RUSSIA.
The vintage tubes I tried that didn't make the cut include labels like JAN Phillips, Hungary, Japan, ECC83, and some newer Mesa's, SPAX7A's and EH's. I also tried a similar variety AT7's, AU7's, and AV7's in the V2 position. Nothing interesting there.
With great distortion comes great responsibility.
