The Tungsram is the definite winner in several other 12AX7 shootouts, so I was curious how it would perform in my setup. There are some things I like about this tube, and other things that I don't. To start with the latter, I don't like the clean sound, too much bottom. The rhythm is a lot better, the mid's a little mushy but not hollow at all. The lead sound lacks some character, but it too has that same pleasant nasal feeling, and provides enough gain for playing staccato power chords.
