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 !

I just purchased (3) of these tubes for my Budda Superdrive 18 amp. I had a gift card from last Christmas for Guitar Center and needed some new pre-amp tubes. Groove Tubes were the only 12ax7 tube that my store stocked, so I figured I'd give them a try- contrary to my prior opinion on Groove Tubes. The sales associated persuaded me to step up to the gold series 12ax7-R. As soon as I pulled the first tube out of the box, I notice that the sticker for "Groove Tube" wasn't properly placed over the encryption on the original tube stating it was a "Sovtek 12ax7-wc." A tube less than half the value! Groove Tubes is taking cheap 12ax7s, stamping their logo on it and selling it for more than double the price!! Don't make the same mistake I did!

I didn't get the tube with the sticker.

By Aaron Adkins

from Syracuse, NY

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

I can't speak for anyone who got one of these tubes with the sticker on it, since the one I got had the screen printing on it; however, the product number on the box my tube came in matches the one listed. The pre-amp gain on my Rivera Hundred Duo Twelve was fizzing out, so I popped this into my V1 position and, crikey, it made a world of difference in tone! Very pleased I purchased this tube. Again, I can't attest for anyone who got the tube pictured above but the one I just popped into my amp sounds awesome.

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

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

      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.

          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!

          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.

          DON'T BUY!!!

          By R.Barajas

          from Salida, CA

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

          I should have payed more attention to the other review. 12AX7-R?, NOT!, the sticker didn't even hide the orignal stencil, SOVTEK 12AX7 WC These tubes are adequate at best, sounding somewhat dull and flat, mids and highs sound muffled. If your looking for an inexpensive tube on a tight budget, the SOVTEK at 9.99 is a good deal. But to be relabeled as something it's not, and to charge more than twice the price 21.99? a ripoff at best. Don't waste your money on Groove Tubes.
