JJ ECC83 / 12AX7 Gold Pin Preamp Vacuum Tube
These are the gold pin version of the standard ECC83. These tubes are immediately discernible from other 12AX7. They have a construction that is similar to a frame-grid tube - similar to the Telefunken ECC803s. This construction makes them very rugged and reliable. This is one of the best new 12AX7 for any guitar amp. It is very musical - rich with great harmonics. An excellent tube in all Marshall amps in the three preamp positions.

Compared to the Gold Lions B759/ECC83 which I had been using, these tubes are more open, have more gain and more bass and are equally detailed.
Best buy for the price.

First of all, you have to use the tube comparison tool on this website. The description of the JJ ECC83 / 12AX7 Gold Pin Preamp Vacuum Tube was everything it said it would be. I couldn't possibly be happier with how this experience turned out. The tone was warm and hardly any noise at all, which were two of my requirements. The packaging was stout as well. Overall, it was a good experience.
