So it doesn't interfere with the fundamentals?
Should work if you tuned the filter a bit flat.
OTOH, your caps across the pickups, what's their tolerance?
Or put this way, how many did you try until you were happy with that  
resonance?

hehe, what else?  ;-)

What about muted sounds, how does their harmonic structure change,  
when the Stick is modified this way?

"crappy" in terms of "I'm a good OpAmp" ;-)
I'm remember that, we talked about that in Frome.
I just got this idea to get best of both worlds.
My experiments will show whats possible (or what I can achieve) ...

Nah, I'm bound to +/-15V. So that's no issue.

hmm ... lets stick together ... errm ... ;-)

    Looking forward to ...   m.
