      Comments about Groove Tubes Silver Series ST-12AX7-R3 Preamp Tube:

      These babys are not too bad for a poor college kid! Other than the fact that MF gave me one gold series tube in a silver box (I can't complain, it's a better tube) and one of the pins was bent I had no issues. I'm actually warming them up right now and about to play. They are smooth and warm when clean and very crunchy and funkadellic when distorted. I would most reccomend for a bluse style and my rig is a VK112 with GT silver tubes all arround (other than the one gold) and a Patriot Swamp thang.
