GT 12AY7 tubes pass every Groove Tubes premium certification for microphonics, hum, physical characteristics and function.

Outstanding and consistent performance for mixing and matching to get a signature tone from your amp. Low-gain tube used in very early Fender amps. Great for harp or blues where softer, more compressed distortion at lower volumes is desired.

Can sub for a 12AX7 to lower gain and produce a warmer tone.
