The upgrade tubes sound alot closer to the 5151

[fy]

Hey i have exactly 5 microphonic preamp tubes so i thought hey i should change them all 6. As well as the power tubes, I got a matched quarted 6L6GC-STR from TAD soon. But for preamp tubes i am abit confused. My amplifier is Bugera 6262, not the infinium version and 4 of them are 12AX7C, 1 of them is 12AX7A and the other one is 12AX7B. I can't find anything but Groove Tubes if i look for 12AX7C or B or A, but i'd like to get tubes from Tung-Sol and but they're labeled as just 12AX7, my question is are they interchangeable? Thank you so much!

Euuuuh... how did you get that clean sound with a humbucker? (low guitar volume knob as well?)
