    Comments about JJ Electronics 12AT7 / ECC81 Preamp Vacuum Tube:

    Used this as a replacement in a Behringer VT999 pedal. Replaced the stock 12AX7 which was crazy "hot". The 12AT7 is probably still to "hot" in the VT999 but it tames it so the pedal is usable.

      I used this tube to replace the stock 12 AX7 that came in my harmonica amp. Definitely gave me more clean headroom. At this price, give it a roll!

          Comments about JJ Electronics 12AT7 / ECC81 Preamp Vacuum Tube:

          I put this tube in my MXL mic and WOW what a difference in the sound . The mid's seem to come alive with a nice round punch. Very nice upgrade from factory tube. Ive tried a few vintage tubes RCA & GE these tubes really were the best in there time. Finding The right tube makes all the difference in all your audio gear. JJ'S would have to be right up there with the best!

          I have a Vox AC4 and I replaced my stock 12ax7 with one of these tubes. It definitely gave me more clean headroom which is what I was looking for but it's not quite as thick as I was hoping. Overall a good tube though. It accomplished my purposes

          Once again if U can't find em in NOS try em out I have used them all as in them all. The pins are always straight and the tone is always dead on. These are all that go in all of my gear. I would stack em up with the Mullards anyday. And the price here is a good as any I've found including the tube depot..
