I think an upside-down Swoosh-hole would look nice. You could line the inside of the bass with some interesting wallpaper...
.
How would it look if I mounted the two control knobs on the back of the pickguard rather than in the body?
It works nicely for P-basses. And it lets you add or subtract knobs with a PG change.
Yeah, it also means no screwing with an access plate in the back or fishing stuff through a bottom f-hole. Easy to do mods or repairs too. I think this is the way to go.
There is considerable virtue to not needing that access hatch!
I like that look a lot. My only concern might ne the top knob getting in the way. If you were to swing the cut away part of your PG template toward the bottom a bit more you could set the pots more horizontally.
Very nice! Working hard to day Bill or getting a head start on retirement?
