According to both the "12AX7 Comparison of Current Made Tubes" chart and the product review above, these shine in high gain applications. Keep in mind, tube tone is subjective and can not guarantee you will have the same experience.

Would this be a good tube for a Marshall VS8040? It was made in 1994 still has the original tube. Thanks!

Tube selection is highly subjective and although some would consider this a great tube for that amp, other may not feel that to be true. We suggest referring to our 12AX7 comparison of current made tubes: https://www.tubesandmore.com/tech-corner/12ax7-comparison-current-made-tubes

Tube tone and performance are subjective, but to get an idea how this may work in your amp, you can compare them to the tubes currently in your amp using our 12AX7 comparison chart: https://www.tubesandmore.com/tech-articles/12ax7-comparison-current-made-tubes

Product Reviews
This is my go to 12ax7 for vintage Fisher and Scott restorations. Wide open soundstage and sonically flat response. NOS tubes are too expensive, and the sonic differences are marginal at best. A good tube should be neutral, and for me these tubes deliver on that. I will say that the bottle is a bit larger than a vintage RCA or Telefunken, requiring slide on tube shields to be expanded a bit. Otherwise I have thousands of hours of run time, with zero issues so far.
Big improvement for my Hiwatt Custom Little D. Gets closer to DG sound.
This has become my goto 12AX7 for vintage Fisher integrated restorations. Solid performer across the audio spectrum, and so far no reliability issues.
Nice sounding tube
I always prefer this one for the first gain stage of guitar amplifier of any kind, Fender or Marshall or whatever it is. And can get good satisfaction from my customers as always. I don't put it for the later gain stage though.
Bought these to use as preamp tubes in a Peavy VMP-2 Mic Pre. They sound great! Super warm and full range.
This is my first choice in 12AX7 tubes, Very balanced tone
