The Groove Tubes Gold Series GT-6L6-GE Matched Power Tubes Medium Duet provides you with stunning clarity and tone reminiscent of the sounds created by a wide range of classic performers, from Carl Perkins to Jimi Hendrix, both of whom mostly recorded through Fender amps at a time when this was the only tube use worth using. The GE is a faithful reproduction of the original "clear top" 6L6. The flagship of the GT 6L6 line, it looks and sounds exactly like the original G.E. tube used by Fender in the ‘50s and ‘60s. It took more than four years to develop, and has stunning clarity and power.So recapture that sound with these vintage re-creations.

Low-rated tubes have early break-up and distortion, wide range and softer attack good for rock and blues solos. Medium-rated tubes offer normal performance, great dynamic range/attack and are the best all around rating type for all styles of playing. High-rated tubes have the most dynamic range and the most clean power/less break-up for power players, jazz guitarists and bass amps.

I've had the good fortune to compare these side by side with NOS GE clear tops. They are very close. This is good. Will they make me stop collecting RCA black plates? No but, they are very close to the original GE's. The commenter who complained about the "heat reflective" coating on the side is just plain confused. The Silvery looking coating is called the Getter. It's usually barium and it's purpose is NOT to reflect heat. It's deposited in the tube to absorb any air that might sneak through the seals at the pins. So long as it's silver it's OK. As more air sneaks in it gets thinner finally turning a cloudy white/clear. Having the getter on the side is just fine. That's how GE made them in the old days and so did RCA. Sylvania liked to put the getter in the top. Nothing wrong with that either.
just to start of i have been running Groove Tubes for over 20 years now have good ones and a lot of bad ones. now that is said the 6l6chp suck, most of them suck, i needed a pair of 6l6 tubes for a gig and could not wait to get some jan 6l6 off the internet. so i did not have many options so i pick up a pair of gt6l6 ge. anyway so far these tubes rock big time, i have them in a deluxe reverb with a vibroverb power and output tranny, this amp is real loud anything above 4 and your ears will bleed big time.
One should beware of reviewers who sound authoritative but aren't. The 'silver' (barium) inside a tube, called getter flashing, is there to absorb stray oxygen. To my knowledge it was always on the side of GE tubes. It is not "heat reflective" and it is irrelevant whether it is on the side or top.
Groove Tubes are a reseller. They buy, test, rebadge, pack and sell tubes. Their reputation was based on the quality of their screening process. Not sure if this is the result of the change of ownership by Fender now, but I got a quartet where EACH ONE of the four 6l6GC tubes had the heat reflecting silver plating totally of on the side of the glass as opposed to the dome. Unacceptable. KMCMusic (GT's national wholesaler) was willing to replace them, but I had to pay shipping. Not worth the extra money.
I have a Mesa Boogie 50/50 stereo power amp that I run with a POD X3 Pro. I had this set for only a year and I experienced tube failure. As far as tonal quality, the tubes sounded very clean but not sterile and they were able to add to my tone where the X3 Pro ended. I just wish they lasted longer then 1 year.
I put a set of these in my late 70's Fender Vibrolux & they brought my amp back from the dead! They take any thing you can throw at em! They sound great with distortion or clean. Really fun to use natural distortion. Turn amp up above 6 & they go nuts!!
I was highly skeptical at first about buying these when one of my Soviteks went bad, because I had had a bad experience with Groove tubes 15 years ago. My local music store owner assured me he would stand behind these GT-6L6-GE Gold Series (#7) tubes all he way if I didn't like them or had any issues at all with them. These are not cheap tubes, but I bought them anyway. As usual, I customarily replace all screen resistors before any output tube changes in my old Fender SFTR-UL 135 watt. I biased it correctly and let the tubes burn in 24 hours, then rechecked the bias again and found no drifting.The tubes sounded absolutely beautiful. Truthfully, I hadn't heard that amp sound that good since I bought it new back in 1977. Four gigs and one one concert later, these tubes are still sounding just as great with no noise or problems whatsoever. I highly recommend these to anyone wanting a high quality, dependable set of tubes.
I have 4 of these in a Peavey Butcher 120 Watt. They sound much better than the Sovteks they replaced. They took awhile to finally break in and produce distortion, though.
I thought I would "UPGRADE" over my old Sovteck's so I bought the GT's. These tubes sounded great at first. I had my tech set the voltage for them on my Victoria Vintage '59 tweed and burn them in for about 10 hrs and then rematch them. All was well until I got to the gig. When I turned on the amp for the sound check, there was a loud fisssst and one of the tubes blew and turned white inside. Kind of a bummer. Thank goodness I still had the Sovteck's at home. They sounded great and have lasted several more years!
