I bought a set of 5 to upgrade my stock Carvin MTS 3200 head. I've had this head for six years and it has never really satisfied me. When you look at it you see USA quality but I could never get the sound I wanted. The hi-gain channel was just was not right for me. I had it packed away for the last 3 years and a few weeks ago I decided to give it another try thinking it was a good candidate for Ebay. I spent hours trying everything...I got good but nothing satisfying.The clean on this was always great...it was the hi gain side that stunk. I changed the stock pre-amp tubes to this and the results were amazing. The distortion and reverb had a huge improvement. In just seconds I was able to get the sound i wanted. The transformation was stunning to say the least. Next up, the power tubes....but for now my Carvin MTS3200 is smokin hot.

I bought one because they are described as high gain and I thought it would sound good when I wanted extra distortion but it sounds like a cheap wore out tube. I'm gonna stay away from Groove Tubes as there are much better tubes on the market. Try a Tungsol, JJ, or a Electro Harmonic, they sound much better.

Dont blame Groove Tube

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

My experience with tube is that it stinks. Typical of any other Chinese preamp tube i've ever heard. Groove tube is an importer and Re-seller. They grade and select and rebrand. Many of the tubes they Brand are outstanding tubes. The Groove Tube 6L6GE is a fabulous tubes and the only New production, American made power pentode in existence (made by groove tube in California).This 12ax7 c tube is OEM in many many new amps.It is made by shaugang and came stock in my Orange amps (OR30 and Tiny Terror). Do yourself a favor and become educated about tubes: "NOS" New production. What they're called and where they are made.

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

This tube was too dirty to use in position one and position two of my Fender Hotrod Deluxe, however, it sounds great in position 2 of my Hotrod Deluxe with a Groove Tube ECC83-S tube in position one.

Groove Tubes relabels tubes, but these do well

By jenksdrummer

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

Given that I just bought a bunch of them and are happy...SO FAR...I'll probably buy more of them when it comes time to get more.
These are Shuguang tubes, bought in bulk by Groove Tubes, tested, labeled with Groove Tubes logos and so on, and sold.
There's nothing really special about them compared to other tubes, other than GT tests them.
7 for this one, because I've purchased around 20 of these, and had 1 that was bad, so a couple stars off for that, and, the ones that are good are *borderline* microphonic...but they have a VERY stong output...which (simply put) higher-output = more prone to microphonics. These are borderline - meaning if you crank up the gain, and point your guitar just right at it, it will give the microphonic feedback squeal, but if you tap them, they don't ring or pop or anything like that - so, physically they are spot on, just have a very high level of output...

But, in real-world application, that won't be an issue...so I enjoy their stronger output,
GT charges quite a lot for their tubes compared to other tube vendors, but with the idea that they give the buyer value by testing them so well and weeding out the bad ones.I went through MF to get these instead of my normal channels because I didn't feel like waiting for shipping and, as I found out, MF's return policy on bad tubes is great - they took back the bad one and sent me a new one.

Great Tube

By Brad Ovard

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

Get this if you like to have variety in the sounds you get out of your amp. I always play around with different tubes in different slots. That's the real benefit of a tube amp. You can always dramatically change the way it sounds with a quick tube change.
Very unique sound. It has very good clarity and is my favorite in the V1 position for cleans. I use it in the Phase Inverter position along with JJ's in V1 & V2 for awesome distortion & dynamics. It's just a great tube.
Seems very reliable.
Great tube at a great price.

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

Just put 4 in my jcm2000. It sounds 1000 times better! I was concidering replacing my amp with a 6505+ cuz I was unhappy with my tone. I thought I would try the tubes first and I was blown away! Don't waste time on other tubes, Groove's are the best! If you play metal, get the "R" russian model, very heavy sounding.

Very nice tube

By Just me-Su.Ci

from Kenosha, WI

See all my reviews

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

I've used this tube in my 65 Blackface Deluxe amp for a few months now, and it sounds remarkably similar to the Groove Tube 12AX7-M Mullard clone. Both are Chinese tubes, so they may even be from the same manufacturer. The Mullard clone runs 20 bucks apiece, so this is a better buy, but still pretty pricey. It really delivers the tone, though, so I think it is worth the extra $$. Very even response, not too bright like the Sovteks. Moderate, but good gain. I find the EI Elites a little too hot, too much gain. This one is more reasonable in the gain department. Beautiful, even response, not too bright. Fantastic in old Fender amps.

              I got a set(3 tubes) of these for christmas for the preamp in my peavey delta blues and all I have to sa is it makes the cleans rattle the house... i dont like shimerey-shiny highs(they hurt your ears) that are just really loud; i like pristine clear, some what mid driven tone with a lot of low end that shakes what ever room you're in. THESE WILL GIVE THAT TO YOU!!.. sweet tubes.. verry versatile. they make your knobs waaay more sensative - i reccomend these tubes

              I swapped out the stock tubes that came with my Fender Blues Reissue amp. I know this echoes many of the other reviews, but...WOW! I play a '71 Thinline Tele and run through mogami gold cords and a Boss ME-50 board and the lead guitar player in our group thought the tone from my amp was WAY better with these. I couldn't be happier with how these chinese tubes added body and timbre that I was really wishing for.

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

              I've been playing guitar for over 30 years. I used to play British invasion covers through early 80's metal and now I only play diverse instrumental stuff. Your guitar choice, amp choice, pickup height and playing style are all very important in getting your desired tone, but after reloading my Marshall JMP-1 several times with other tubes and recently with the Groove Tubes 12AX7-C (2 of them) all I could say when I plugged my Gibson Les Paul into the JMP-1 was WOW! Warm tones on the clean end, Fat Billy Gibbon's (Blue Jean Blues) semi distorted tones on the 1st distortion setting and saturated harmonic magic with the maximum distortion preamp settings. For anyone into that fat, full tone that made tube amps desirable in the first place, this is the preamp tube for you! If your sound is thin with these, you have other issues to deal with!

              I love electric blues,and, play the blues/blues rock,and SRV/ABERT KING/BERNARD ALLISON/JIMI HENDRIX/ tones are what i love to play.I wish i know about,and,tried the GT-12AX7-C long time ago.
              Recently,i needed 4 new preamp tubes for my Weber vintage amp(similar to fender bassman). I ordered 8 GT-12AX7-C,and received them.And,when I replaced the old preamp tubes with the 4 new GT-12AX7-C/ to my surprise,i ended up with SRV/ALBERT KING/BERNARD ALLISON/JIMI HENDRIX/tones.Wow!...Now,i am going to replace all the preamp tubes of my Rivera Amps with these groove preamp tubes (GT-12AX7-C)From now on these GT-12AX7-C will be my favorites for the rest of my lifetime.
              Best of the Best warm and fat preamp tubes.
              they worth the price.

              I just picked up one of these to replace the tube in my Epiphone Valve Junior head. It came with a Sovtek that sounded alright for a while but after it started to sound thin I swapped em out. The groove tube is definately better...it sounds warmer and the overdrive is alot richer when you really crank. I'd recomend it to anyone.

              I've tried just about every other tube out there and I keep coming back to these 12ax7c's. I use them in all of my Fenders now. They have all the Harmonics and warmth you could ask for. Plus they sound great through the COMPLETE tonal spectrum, (Highs, Mids, and Lows). They sound great clean or in the gain channel which is very important to me. For me these Chinese GT12ax7's and the JJ/Teslas are strong contenders for best current production 12ax7. Like I mentioned earlier I've done the A/B test with many other 12ax7/ecc83 types and to me these just sound right!!!!

              I accidentally put these into my Twin 1965 reissue instead of the Russians, without realizing. After breaking them in I found my tone was "dirty" sounding with no "color". It was also rounder and less alive. I finally figured out why my amp sounded wrong and placed the Russians back in. Now my tone is very clear and colorful sounding, as well as brighter sounding. I love Russia!!! I can't even explain how happy I now am that I found out why my tone sounded so wrong and put those Russian beauties back in.

              I put this in V-1 of my HiWatt. I noticed it right away.I run Tung-Sol in V-2 and V-3.It's a rich & smooth distortion when you overdrive it. Even the cleanest settings are warmer with "tube vibe" between notes. No one would regret putting this in their tube collection. Have fun!
