GROOVE TUBES

Groove Tubes® GT-12AT7 (Single)

GT-12AT7 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.

Durable design that can be used as a phase splitter or driver tube. Excellent in vibrato or reverb circuits where consistent, high output power is desired. Can sub for a 12AX7 to lower gain and produce a slightly warmer tone.

Groove Tubes GT-EL84-S Duets Tubes

Exhibits many of the same characteristics as the EL34, but with a power output of roughly 5-8 watts. Very creamy and smooth; used in Fender Pro Junior™, Blues Junior™, Vox® AC30 and AC15 as well as many modern class ”A” amps. Nearly every modern tube amp company produces a small amp, and Groove Tubes EL84’s are a perfect upgrade for the stock EL84 tubes in these amps. Great for recording and rehearsal; with a soft and tactile touch, rich harmonic response and pleasingly musical top end.

A solid performer – good quality and long lasting. Tends to be a little more aggressive and edgy when pushed into overdrive. This version is a little brighter, but still has a smooth top end.
