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

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..

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!

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

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

Tamed my Fender Hot Rod Deluxe

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

    I wanted to be able to use my Fender Hot Rod Deluxe at lower settings at home. Stock the amp is very loud when dialing in the volume - almost impossible to set reasonably for home use. Changed one preamp tube 12AX7 (farthest on the right when looking from the rear of amp) for the new 12AT7 and cut the gain. Amp is now awesome to use at home as it can be turned down to decent volume. The tube lowers the gain by about 40% but the amp is still a beast and easily can be still used on stage. If more volume is needed in the room, mic and run to PA for additional volume..... Sweet and easy fix.

                    I should have tried this in my phase inverter position years ago... It sounds so much better. I'm am using in my Bugera 333XL.

                        I bought this to put in a Marshall DSL 15c. I was not really happy with the early compression, and the fizzy high gain on the red channel. I did a small mod to the circuit board, and changed the speaker. Both of these helped a little. Replacing the stock 12ax7 with this in the V1 spot made all the difference. The amp sounds great now. Both channels are better to my ear.

                          Had to replace the original off my '82 Fender Super Champ due to reverb function loss. Before buying the uber expensive and defunct 6c10 tube, I thought to replace this first. Can't go wrong with JJ's price and quality. The reverb comes alive once more. NOW, if only JJ makes the 6c10!!!

                            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.
