The designs don't seem original enough so not sure I like them enough to have one built. However workoffire is local and has the resources to do something for me if I so wish.

Probably go for a single in the neck and cool rails in the bridge.
I quite like the idea of using some roller knobs (not shown) as a volume for each pickup, ala jazz bass. On a separate circuit using a regular tele pickup selector along with volume & tone so I could have a option of either/ or.
Which do you prefer aesthetically ?
