Bought one just to try it out on my Bravo Audi, first one was a dud, so I got a replacement one, and that one was a dud too. Inside the tubes you can see a wire turn bright hot red, I don't think that is normal. I made sure I bought the right model for my amp, but they didn't work properly. Next time spend a little more and get a good brand.

I bought these tubes to replace the Ruby 12ax7 tubes that I had in my Peavey 6505 plus 112 combo amp. These tubes are perfect for what I wanted and would not hesitate to buy them again if they blew.

Great tube choice for the V2 and V3 spots in a Fender Blues Jr. or similar amp. This tube is articulate, well-balanced, and provides pleasant, round low midrange response. In the V1 spot, it's a bit dry and can get shrill in the treble frequencies, yet not as much as similar Tung-Sol or Groove Tube alternatives. Overdrive is soft and natural with decent harmonics, yet it sounds a bit 34;boxy.34; Great and reliable option, though better alternatives are available for the V1 slot.

Really happy with these preamp tubes. I just re-tubed a bunch of old amps, and simply couldn't afford to stick the spendier stuff in all the tube slots, so the JJs went in some of the more 'general purpose' slots, like the normal channel 34;first34; tube on 3 different older Fender amps, and also in the 34;recovery stage34; tube that comes after the reverb circuit. Some folks claim that these sound 34;less 3-D34; than other tubes like the (new Russian manufacture) Tung Sol 12AX7s, but I really can't hear a difference.

These sound great and have really good gain but not microphonic.
