Groove Tubes GT-12AT7 Hand Selected ECC81 Guitar Amplifier Preamp Valve

The Groove Tubes GT-12AT7 preamp tube is manufactured to the highest quality JAN spec. NOS, made in USA for extremely long life. Used widely in most U.S.-made amps and, in particular, Fender amps. Fender amps with reverb use 2 - 12AT7s - one for the reverb drive stage, and one as a phase inverter to drive the push/pull output stage.

The makeup of the 12AT7 is very similar to the 12AX7 and it can be substituted for a 12AX7 in a pinch. Some players prefer the 12AT7 in the driver stage of a Marshall for a cleaner, brighter tone. (The driver or phase inverter is the 12AX7 located nearest the power tubes.)

The 12AT7 is rarely used in a tone-generating stage, but rather in function stages, so the Groove Tubes GT-12AT7 is selected for durability.

Durable phase splitter or driver tube. Excellent in vibrato or reverb circuits where consistent, high output power is desired.
