Get 'em NOW
I have played guitar for 50 years and never had the beautiful tone and responsiveness I get from these 12AX7s. When I first turned the TSL100 on after re-tubing I was stunned to hear the pick noise and my fingers touching the strings. Everything is captured. And the reviewer who compared the tubes to instant mastering was spot on. The sound these produce is so polished, so fitted to the human ear's response curve, that you just can't help falling in love with them. True magic in a bottle. The nearest automotive equivalent I would offer is getting an instant 200 more horsepower from a bolt-on supercharger. It's that dramatic. The V1 holder is crying out for one! Act now!
