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.

    I put these in my Hot Rod Deluxe. The amp has never sounded better.

    Used these as a replacement for the original Miniwatt tubes in a Kriesler 11-95 radiogram from the 70's. Excellent bang for your buck. Work as expected. Would highly recommend.

    The JJs are my go-to tubes for my AC15. They're rugged and inexpensive, and they are well-balanced with breakup at fairly low volume.

    Whether you are looking for good performance or low price, I can recommend the JJ 12AX7. I have it in a number of guitar amps (some that I built) and a hi-fi amp (that I rebuilt) and they work well in both applications.

    I use this tube as my everyday listening tube currently. I favored it immediately above new production Tung-sol which came with my Jolida Tube Dac III (I have 2 of them, which allows me to A/B them).

    There was more harmonic information and slightly more warmth, but plenty of crisp high frequency detail and air.

    It is a very coherent sounding tube that faithfully plays back music with a sense of the whole recording; it doesn’t try to dissect the recording, while still allowing one to follow individual aspects of a performance if desired.

    It gives you that bit of “extra” that solid-state always seems to lack on stringed instruments, voices, timbral resolution, etc. It is subtle but noticeable, which will please those who don’t want to veer into tubby rolled-off sounds.

    Compared to a new production Mullard, it is a little less boisterous, in terms of its presentation. The Mullard gives a little extra “extra”, relative to my comments above.

    However, while the Mullard is slightly preferable with classical, jazz, small ensembles and acoustic performances due to its highlighting capabilities, one might argue it is a bit less refined and coherent, especially when pushed hard. This isn’t bad, just different. Even certain metal tunes can sound great with the Mullard, but it sometimes loses its composure.

    So then, the JJ ECC83s, is a stellar all-rounder and a very satisfying tube.

    Highly recommended!!

    I installed three of these in my 2000 Marshall 1959SLP and they sound great. I highly recommend.
