For violin!
Nicodraps, 25.03.2020
Powerful and precise! I use it in a special condition so... Hard to give a constructive comment. It's used in a fender blues deluxe reissue with a Zeta Jazz Fusion (e-violin). The fender in my case is used to have a deep sound but clean, this amp is not specially for that axed more blues & rock, but with a low volume and this tubes it's clear deep and warm too, great. Lot of dynamics, very graduate. Perfect!

Great tube everytime.
petrix, 10.12.2019
I have a rather large stock of NOS tubes, and while I'm not a tube snob, I do know my tubes. I have never been disappointed by any Groove Tubes and I trust them to hold up under duress. I build, sell and repair tube amplifiers . I won't hesitate to use Groove Tubes for a performing musician who demands absolute reliabliltiy and durability. I have a lot of choices, but I use the GT-6L6's in my Bandmaster.

THE BEST TUBES OUT THERE !!!
chicken picker , 11.04.2019
These GT are the best tubes you can use for your amp, they last much longer than any other and the tone is superb, also you won't need to call a technician to re-bias your amp if you replace them with the same number of grade, just plug and play, can't get any better folks !!!

Groove Tubes 6L6R Duett
Robert Q., 08.02.2014
These are great tubes, bought as replacements for my Fender Deluxe Hotrod. Once biased they tend to stay that way for longer than some others I've had. I change them out every couple of years so can't comment on life, but I give old ones to other guys and they're still using them....
