Brand preference is pretty fierce when it comes to tubes. Some guys do JJ's and nothing else...some guys, NOS, some guys EH, some guys don't care as long as it's not microphonic.
So what do you guys use?
Me? I've used JJ's with mostly good results...In some amps the preamp tubes are downright muddy....I've also had great results with EH tubes, but they arent as reliable as JJ, as I've had a few 12AX7EH's that were microphonic. I never went down the NOS road....
I hear that the new JJ ECC803 is really giving the GT 12AX7-M a run for it's money....and at half the price of the GT!
Let's hear it!
