Groove Tubes GT-5751-M Select

EXCLUSIVE GT model.

This is very similar to the12AX7M, but with lower gain and output. Probably

the most forgiving tube in the preamp series, it’s an excellent replacement for stock tubes that sound too harsh. It’s also a great upgrade for any high-gain amp,

for improved definition and stability (less squealing).

Especially recommended for Hot Rod Deluxe™ and similar Fender® and Marshall® high-gain modern amplifiers.

Preamp Tubes

These pass every Groove Tubes premium certification for microphonics, hum, physical characteristics and function. 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.
