Groove Tube Gold Series GT-12AX7-R Preamp Tube

The Groove Tubes Gold Series GT-12AX7-R Preamp Tube is an older-style Russian-type vacuum tube with strong tone and a slightly edgy tone. This newer tube from Russia has slightly brighter and lower gain, quicker compression than the GT 12AX7. Great for most Fender amplifiers, especially lower gain Fender-type amps.
