Hi Mark,
If it helps, I'm still in the middle of that build with the Shadow system under a Fender-style bridge on a 30" body. It got slowed down by me breaking the pickup... I ordered a couple replacements and will report on progress as it happens. I did try the Shadow system on my Fender precision fretless -- it sounded surprisingly U-Bass-like (I have Thomastik Jazz flats on it).
I tried an electric with a piezo bridge (not the hipshot) and thought it had too much high end and string noise vs the shadow electronics. But it had roundwounds so who really knows....
