Fender don't make no tubes... From what I understand, Groove Tubes doesn't make them either. They take other brand tubes, tests them for certain values and conditions, group them together into pairs, quads, whatever and then rebrand them as GT tubes.

So, I'm guessing they add the Fender logo to a certain amount of them and Fender buys them at a bulk rate. Fender installs them in their amps and GT makes a tidy profit. Fender gets a halfway decent tube that's halfway consistent for a reasonable production cost... then they warrant them for a short period of time once you've turned them on. GT improves their market share, Fender brags about using GT tubes....

GT tubes and EH tubes may be the best tube in the world... though my personal experience showed that old RCA's and JJ's were more musical and had characteristics I liked when they were installed in my amp.

Being a guitarist, I spend way too much time obsessing about my tone and trying to buy my way into it... as opposed to what I should be doing more of, and that's playing my way into it...



Seriously, I found the GT and EH tubes that were in my amp 'tight' and unexciting compared to the replacements I put in there.

I have heard reports, but have no experience with the EH tubes failing and taking internal amp components with them. I'd rather not take that chance myself... besides although I loved the way my amp sounded when I bought it, it sounds even better now!

Lance bought an amp off eBay the other day and brought it over. It had EH power tubes and we though one of them was rattling. I had a pair of JJ 6v6's as backups and we put them in the newsed amp. It didn't solve the rattle, but it sure made that amp instantly more musical! We never got the rattle solved, but we definitely made a decision about JJ v EH power tubes!

So, Gt tubes may work for somebody, but with a small investment, I found vast improvement and I'm spending even more time playing.. instead of obsessing
