Vintage Tube Tone for any Amplifier

GT-12AX7-M tubes 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.

An exact reproduction of the acclaimed Mullard ECC83 design, which was the tube found in most high-quality musical instrument and hi-fi amplifiers of the '50s, '60s and '70s. Excellent all-around sonic character that adds vintage clarity and feel to any modern amp — a slightly rounder, deeper and all-around warmer tone with clarity. A lower-gain 12AX7 tube, it is a highly musical, harmonically rich and an excellent performer.

  • 9-pin triode design
