Audio-Voice 12AT7A

I bought this one because it has a lower mu than a 12AX7 (60 as opposed to 80-100), to try it in the reverb follower or the phase inverter section, but it's also nice to try it in the gain hole. It left me with the same impression that the Chinese 12AX7A made: too direct and glassy but with less gain. Even the clean sounds weren't very pleasing.
