Great tone at lower volumes
The 12AY7 is a lower gain (gain factor 45) tube commonly used in very early Fender amps from the 50s. You can swap out your stock 12AX7 and give your amp a warmer tone and less gain. When pushed, this tube produces a softer, rounder, and more compressed distortion and lower volumes, with plenty of low end response.
From Fender: "Quite simply the best 9-pin triode preamp tubes you can buy—specifically designed and tested for musical instrument amplification and standard equipment on Fender amps. Outstanding and consistent performance for mixing and matching to get a signature tone from your amp."
