I tried fixing the frequency, but eventually found that, as new strings get 
played, they lose the top end, and so continuously variable frequency was good 
for this, and, of course, if one must have potentiometers, then, one may as well 
make use of the dull/bright sonic pallette that becomes available. The resonance 
is fixed, though. Slightly more on the bass side. The result of a mere 12 
different prototypes, paranoia, and endless testing.

That is a bit different again - a very nice sound, but thicker than what I am 
after. The harmonics on such high-played bass strings are very sharp compared to 
the integer ratio. An excellent aesthetic ("Walk on the Wild Side", is a good 
example).

The crappy 741s are awesome for distortion. If you need more dynamic range, 
there's plenty to choose from, especially if you don't have to run from a 250mAH 
9V battery!

Looks like it :)
