I am no wiring wizard, but Seymour Duncan has a bunch of diagrams on their site.

We also have a wiring group here:

As Dan pointed out, you might get more experienced responses by going to the appropriate discussion group.

I am also not a guitar electronics expert by any stretch, but I will give the opinion that yes, you need to avoid ground loop circuits. That is why you dont wire your grounds with multiple routes. Reduces noise and feedback problems.

Grounding the strings via the bridge is considered the standard route to reduce hum. A conductive pick guard needs to be grounded too.

Some people would consider it critical to A: have a grounded outlet to plug your amp into, and B: make sure the ground prong in the outlet is actually grounded. I have been electricuted, but never through a guitar because of a freakishly unlikely short that delivers high current through a guitar chord. But on the other hand I guess I would like to keep it that way. I also dont stand in a thunderstorm in the middle of a field on a hill holding a golf club over my head........ Just a thought.

The preamp wiring needs to be wired per the preamp manufacturers instructions. I dont recognize  that part of your diagram, cant tell you anything there.

Most of the people I have talked to advise against mixing pots.

If your circuit works as I suspect it is intended, you may want to know the piezo might not respond to the tone control pot. They just dont work the same as a mag pickup. Unless the tone circuit is part of a piezo preamp.

Thats all I got, and its probably well below the 2c worth line.

Thank you guys.

 

Thank you Mark for your guidance and words on electricution! I guess i´ll have to do some more soldering work for the grounding to avoid the hum then. The tone pot dosn´t necessary have to respond with the piezo but of course it would be nice if it did. Concearning the blend pot... I´ts such a nice thingy if it just would work. Why people don´t lik em I dont know yet but i think I´ll try it out for this project and evaluate it.

 

Once again, thank you for your advice. I´ll now move this question to the electronics forum.
