How do these differ from regular jjs? Are they worth the price difference? Im using a bugera 6262 and would like to get smoother/creamier gain as well as an increased tightness and less muddyness.
The regular ones are fine. Replace V1 and V2 with a JJ and the rest of the preamp with EH 12AX7s, and get the regular JJ 6l6s. That should be plenty smooth.
