A Warm-sounding Preamp Tube from Groove Tubes!

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

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 12AX7C Preamp Tube is new offering from China, featuring a warm, round, and fat tone - not too bright. The 12AX7C is great for Marshalls and Fenders, while its sweet, warm midrange tone complements the tonal properties of European amps. This tube takes some of the edge off of high gain amps by reducing the brightness while still having the gain and articulation. It's ideal for those who change first stage gain preamp tubes to change the taste and character of their amps (remember, this can be done in less than a minute without tools, adjustments, or a "tech"). This is one tube that should be in your basic toolbox.
