A couple of months ago, I found a few Groove Tube boxes I had stashed away that are white and grey on the ends that look a lot like the picture below except they're 12ax7 preamp tubes. Anyway, I put a couple in my Marshall and man have they been sounding great. I have some gold box ones that I bought at the same time which were supposed to be better, but after all these years, I'm really digging these tubes. Anyone else have some of these? What do you think?
