Great 12AY7 for Fender Tweed amps or a substitute for 12AX7s where lower gain is desired. These can be great in the V2 sockets of high gain amps that you want to make more "vintage" sounding with smoother overdrive and less fizzyness.
Just wanted to let ya'll know. My tubes came in, and I couldn't be happier. The JAN GE 12AY7 sounds smooth and really warms up my Fender Blues Deluxe. When cranked, it gives alot more headroom, which is what I was looking for. I will definetely be back for more of your tubes. Thanks!
