Well, there *are* digital potentiometers, right?  Usually with fairly 
coarse resolution, naturally.  But the electronic potentiometers have 
been used for a lot of musical electronics, including guitar and bass 
preamps by ADA and Marshall, and I'm sure lots and lots of other stuff 
(consumer stereo equipment must use tons of those parts).

The two-vactrol approach apparently worked OK for Mesa/Boogie, as I've 
never heard anyone say anything bad about the TriAxis.  As long as 
you're not expecting a lot of linearity, it probably will get the job 
done.  And the Fender tone control circuit that they replaced with the 
vactrols was plenty interactive to start with, so it's probably the 
ideal application for a two-vactrol "pot".
