this is such a beautifull bass!

Nice job on the routing, looks great! I see you covered up one of the f-holes. Was that to control feedback? If so, why only one hole and is it effective?

Edwin, also, are each of the pickups and the hum cancel pickup in their own compartments and isolated from the other electronics in the larger compartment? Thanks!

The F-hole is covered to provide continuous shielding. Not only has feedback not been a problem, it's even difficult to get when I want it. This bass is completely resistant to feedback, or maybe I just don't play loud enough! :-)

Each pickup has its own rout, but the routs are not shielded. The pickups themselves have all the shielding they need. Noise actually decreased when I took the shielding out of the pickup cavities.

Or maybe I don't understand the question.

Bass looks great. Cosmetically I like having the hum canceler visible and the new pickup selector knob looks much better, too.

Interesting that trying to shield the instrument resulted in more, not less, noise. Your description of the process makes it easier to understand why Ron has to fine tune the electronics in each bass after the hardware is installed.

Bringing her back to CA in May?

I think so!

Looks good - but with the hum-x up front, where will you put the quad p/up???

Why, piezos in the bridge, of course!

Actually, stereo is good enough for me.
