That depends upon what you consider significant. Amps/music is the world of subjectivity and what's significant to one player is subtle to another.Originally posted by daddyo
Is swapping one 12AX7 tube for another going to make significant tonal difference in an amp that was designed specically for a more classic, lower gain sound?
Lots of love here for the NOS RFT, and it is a great tube, but I find that they are too dark to place in more than one position in any of my amps. I have one in V1 of my JCM 800 and its just right, place another in V2 and it gets a bit dark - plenty of gain though!!Originally posted by goneracin
+1. Best higher gain ecc83 IMO. Also does something sweet in a marshall type circuit
