The Groove Tubes Gold Series GT-12AX7-R Preamp Tube is an older-style Russian-type vacuum tube with strong tone and a slightly edgy tone. This newer tube from Russia has slightly brighter and lower gain, quicker compression than the GT 12AX7. Great for most Fender amplifiers, especially lower gain Fender-type amps.

    The Fender Rivera era tube amp sounded muddy and micro-phonic

    this one GT cleaned it up and made the Super 60 roar again.

      Comments about Groove Tubes Gold Series GT-12AX7-R Preamp Tube:

      I messaged the support team here at Musician's Friend and told them I wanted to upgrade my presonus tube channel strips with something vintage. They recommended the GT-12AX7-R. I ordered two and installed them in my preamps.

      I'm satisfied.

      Comments about Groove Tubes Gold Series GT-12AX7-R Preamp Tube:

      This is not a bad tube, in fact it's a good tube. It's just that I can't find anything outstanding to say about this tube. It's a good replacement tube for an amp or an amp's channel which is dedicated to clean tones.

          Upgraded two Presonus Studio Channel's with these tubes...

          Increased warmth and more usable when overdriven.

          Nice & Creamy.

          Comments about Groove Tubes Gold Series GT-12AX7-R Preamp Tube:

          Needed to re-tube my Blues Jr....ordered power tubes and three 12ax7's...all good until i installed one of the 12ax7's. Very bad hum no matter where i put it V1, V2 or V3...replaced with old tube until the hum went away and narrowed it down to one tube....MF does the right thing...I like these guys. call them, they say no prob and 2nd day me a new tube...unfortunately it went out on friday so won't get it till monday...am playing this weekend with only 4 new tubes...I presume all will be good when i get the replacement. but doing biz with MF, in my experience, is usually hassle free. BTW the sound is very good with new power tubes and new preamp in V1 and V3....maybe better with all new tubes??

          Comments about Groove Tubes Gold Series GT-12AX7-R Preamp Tube:

          This Russian tube really is just a relabeled Sovtek, which is a good and bad thing. Quality and reliability is great because the tube is tested both at the Sovtek factory and at Groove Tubes. Compared to the stock Marshall labeled ElectroHarmonics in my AVT50H, the GT is slightly lower gain and brighter. I really wanted a smoother, cleaner sound and that's exactly what I got with this tube.
          For the bad, the tube is priced quite a bit higher than its Sovtek counterpart. Overall, this tube is pretty sweet!

          Great replacement tubes

          By 

          from Bay Area, CA

          Comments about Groove Tubes Gold Series GT-12AX7-R Preamp Tube:

          I bought two of these tubes form my Orange Tiny terror because my amp was making weird sounds and these were the only ones my local shop had. I havent tried too mant tubes, so it didnt really matter which ones I got. Im glad I got these ones. Makes my terror sound much more clear. A little less crunchy than before, but more of a warm overdrive. Sounds great. Worth the purchase.

          Maximum Gain

          By 

          from Upstate New York

          Comments about Groove Tubes Gold Series GT-12AX7-R Preamp Tube:

          I play a lot of 80's, 90's metal and love fast and furious shredding. I own a couple ADA-MP1 preamps , Paul Gilbert influenced me to buy them. The ADA's are old but are a must for myself being a tone freak and recently I changed out the tubes to try these Groove Tube Gold Series and the difference is unbelievable. I have so much gain and sustain now I don't really know what to do with it all. I had to back down my overdrive(s) which is extremely rare for me to even consider. I really wanted to post this review because I feel it is very important to let some know that you really can get a lot of different sounds with different tubes. You don't always need to buy more pedals or effects... sometimes , a quick and easy tube change will make the world of difference. I feel like my amp is now nuclear powered .. it's almost out of control. That may be too much for some , but for shredding and ripping out scales , these Gold Series AX7's almost make me feel like I am cheating on my playing. Plus, I don't need to turn the amp up much at all , it now crunches and screams at low volume's. Love these tubes !
