Comments about Groove Tubes GT-12AX7-R2 Preamp Tube:

My favorite preamp tube. High gain. Improves overdrive and distortion. With these you may find you no longer want a distortion or overdrive pedal. I'd also like to try the JJ ECC83S.

A Groovy preamp tube!

By Shred Fest

from Grand Rapids MI

Comments about Groove Tubes GT-12AX7-R2 Preamp Tube:

I play through a Dual Rec and have tried a few different brands of preamp tubes throughout the years. These tubes work great! I have over 10 hrs on these tubes now and I have only heard good things while using them. I have noticed less hum noise and better bass response. These tubes are more expensive but if tone is a priority then you can't go wrong with this purchase.
