Totally Tweed! The preferred OEM tube of ’50s-era Fender Tweed Champ and Deluxe amplifiers. The Tungsol 6V6 tube has a geometry designed to safely handle the higher voltages used in guitar amps ­ plus heavier plate and grid materials.

From our review of the Tung-Sol 6V6GT: "The Tung-Sol 6V6-GT is an outstanding tube and I feel it delivers a much smoother overdrive that you could describe as creamy instead of crunchy. The sound is better defined than the Electro Harmonix with less compression than EH or JJ."

Good DRRI tube


Amp: Deluxe Reverb RI- Replaces: Original Groove Tubes- Typical playing style: Blues at volume 2-3.

The amp was dead quite with the Tung-Sol tubes. The amp retained its overall tone, but with less emphasis on initial impact or attack of the notes. To me, it sounded more musical and better balanced [overall]. There is substantial detail and I can hear, more clearly, the affect of splitting coils on humbuckers than I could with the GT tubes. Sweet spot for clean tones happens at 5 on the volume [Fat 50 single coil pickups]. Break up starts at 6 and sounds smooth, but falls apart at 9-10. At ten rather than sound "over-driven" it sounds over-modulated. Conversely, the GT were a bit more harsh, but was very usable at 10. I do not believe the amp is as loud with the TS tubes. Normal playing, for me, is 2-3. With the new tubes it seems more like 3-3.5. Overall, for my playing style and volume, the TS are a better fit than the GTs. Very musical, very nice sound. If you generally play in the 2-7 volumes, these are great. If you really push your DRRI, I would seek another tube IMHO.

Maybe not for the Deluxe Reverb


This is a follow up to my post 9 months ago. Everything stated in the first review as well as what is written in TheTubeStore review is dead on correct. In summary, they gave my Deluxe Reverb a more refined tone. Same sonic signature, but a bit smoother on the top end and better attack. Unfortunately, they died after 8 months. I purchased another set and 1 died after a month. I believe the plate voltage might be a bit too high. TheTubeStore was excellent with their help. No issues at all. I paid the difference and purchased a set of TAD tube, hoping they might handle the plate voltage better. Worth trying in your Deluxe? Absolutely. I liked them so much, I might just accept the fact that I replace the power tubes each year.

Worked well; went bad after six months of use


I bought a matching pair of these tubes back in June to compliment my APPJ PA1502A and they were great well they lasted. However, I'm sad to say after a bit of diagnosing the crackling problem I've been having in my headphones for the past few days, it's come down to these tubes being the issue. Now I'm back to using the stock tubes. I'm giving a 3.5 simply because of a short lifespan.
After a quick search, 6V6 tubes should last around 1000 hours -- according to my Last.fm, in the year of 2016 I listened to 487 hours of music, and considerably, half of that should be from June until now. So they may have lasted a good 250-300 hours.

Tung Sol 6V6 comparison


I’ve been using (20-50 gigs a year) several sets of these tubes over last 7+ years. In 5e3, Dr. Z, Fender Princeton Reverb, Egnator amps which span years from 1950s to current. These tubes have had zero issues and always sounded good. I have a good supply of NOS tubes so just for fun today I compared the Tung Sol 6V6 against some old RCA in my 5e3. Result is they are at least 95% similar & I know in a band mix the diff is undetectable. The Tung Sol are my go to except in the Egnator where I purposely prefer the extra punch and mid focus of JJs. With Tung Sol 6V6 being available no one should be worried about copping old school tube tones.



I installed these in a Fender 57 Deluxe FSR 5E3, I'm blown away. I already loved the tone of this amp. Now, it is more mesmerizing. So much definition, detail. Super clean and depth. I replaced the original GT tubes with Tung Sol. Super happy, we'll see how long they'll last. I'll update if they fail like others said. 6, Nov, 2019
