  2. When I owned the 4 PRO, I tried a few different 12AX7 tubes and head no difference with the sound. I feel you are best off using the exact same tubes in there - Groove Tubes 12AX7 or another cheap version of the 12AX7.

    Hopefully someone had has some success.....
  3. Maybe just drop in some JJ's and be done with it :)
