      Comments about JJ Electronics 12AX7 / ECC83 Preamp Vacuum Tube:

      Needed increased bottom end and a less shrill top end to my Marshall DSL 401. These tubes provided just that and a more complex tonal structure. Very pleased.

      Comments about JJ Electronics 12AX7 / ECC83 Preamp Vacuum Tube:

      I had a loud hum on my amp, so I read online that I should change the v3 tube. I purchased the preamp tube and now the hum is gone. Note: Now it could have been my guitar cable or even my cable input on my guitar which caused the hum, nonetheless I also bought a new guitar cable for my axe and now eveything is great. Thank you Guitar Center!

            Bought a set of JJ's to eliminate a nasty harmonic tube shipped from factory with amp. These did the trick and my amp sounds like it should now and more.

            Great Replacement Tube For The Price !!!!

            Comments about JJ Electronics 12AX7 / ECC83 Preamp Vacuum Tube:

            2 months ago, I was lucky enough to have acquired a NM Fender Roc-Pro 700 combo which is a hybrid SS /Tube 70 watt combo . It sounded great and everything but, the seller did not inform me as to whether the tube in it was the original or not and being new to tube amps ( I've always been a SS guy.) , I did not want to take any chances so I ordered one of these. It turned out that the tube which was in my amp was the original which was made way back in 1996 and installing this was a breeze. Right away I could tell that there was a major improvement in the amp's sound from a extra boost in the power, to the clarity of the tone as well. I don't know how long these tubes last but I'm glad I bought it and will be using these from now on.

            Replacement for Pre-amp tube in Marshall AVT 150 H

            By Matthew

            from Rock Hill, South Carolina

            Comments about JJ Electronics 12AX7 / ECC83 Preamp Vacuum Tube:

            I used this to replace an old used tube in my Marshall AVT 150 H head. It actually added more gain to my sound, more smoothness and a more rounded high end. It was what I was looking for. Keep in mind however, this is only my situation, I have no idea how this tube will react with other amplifiers only my Marshall. Sounds better than it did before. -Matt

            Comments about JJ Electronics 12AX7 / ECC83 Preamp Vacuum Tube:

            These were the preamp tubes in my first ever tube amp, so of course after learning about these things I went out to experiment with different 12ax7s. After trying chinese/ruby tubes 12ax7s, vintage sylvani and General eletric, vintage RFT and some other new production tubes I really learned to appreciate how great these tubes are for the price. They are DEAD quit, if you tap them with a wooden stick on your v1 you will hear little to no noise. They withstand the beating of a combo amp just find. If you want your amp to have a more balls bottom end, and perhaps a bit less shrill on the highs, this is the tube for you. After all my NOS stuff I am back simply JJecc83s tubes. Love these things!

            Good tubes.

            By Gabe Ausiello

            from SF Bay Area

            Comments about JJ Electronics 12AX7 / ECC83 Preamp Vacuum Tube:

            I haven't used anything other than JJ's, so I don't have much to compare to, but I did have to replace my old JJ's with new ones, and it made a nice difference. Saturation is good. They are vey quiet. Plenty of gain. Compared to my old tubes, the new ones accept the push from an overdrive pedal much better. I don't have that great of an amp in the first place (Peavey Windsor Head), but I did get back a tiny bit of EQ that I was missing when I put the new tubes in. I would recommend these for sure.
