A Great Preamp Tube for Fender-style Amps!

Note: all of the Groove Tubes tubes and sets we carry are "Mediums," or in the 4 to 7 range..

Groove Tubes has been manufacturing, importing, and grading quality power tubes for two decades. No stranger to Sweetwater, Groove Tubes founder and energy source Aspen Pittman has paid us numerous informative (and always entertaining) visits through the years. His tireless pursuit of perfect tube tone has resulted in Groove Tubes' reputation for consistency and premium quality. Want proof? Fender tube amps now include Groove Tubes as standard equipment, and true tube aficianados worldwide swear by the tubes and pro audio products Groove Tubes makes. For premium tube tone, choose Groove Tubes!

The GT 12AX7R preamp tube represents the sound of an older-style Russian type, with strong tone that's a little edgy. Slightly brighter with lower gain and quicker compression than GT 12AX7, the GT 12AX7R is great for most Fenders.
