After playing w/test pieces and a torch, I decided against the flame-burnishing of the edges as it is tricky business - I've spent a lot of time on the guard and really don't want to mess it up at this point. 600 wet sanding and polishing looks good enough (...for jazz

) Backed it w/white contact paper, both for opacity and also so the paint is separated from the body. It looks like clear glass tile - very subtle and elegant. Coincidentally, it also looks like vintage green/white Fender pg's! (bonus!) The pic doesn't really capture how great it looks against the FGM. ~ Phsshhuuwww! ~
Thinking about pickguards, most all of the contemporary basses out there don't have them. (unless going for a retro-look, like me in this case) I'm not inviting a debate of pro's/con's likes/dislikes - just smiling at myself for getting so fussy about something most bass player would take off if their bass came w/one! Also considering that you can buy a stamped out J or P pg in any number of visual options for very little, mine would be worth a fortune in labor alone!

I like basses both w/and w/o pg's, as much as I like basses painted and not painted/natural wood. At days end, I like all things bass!
The Supersonic "look" was designed to serve both aesthetic and stylistic considerations - and I'll know more about it's "feel" and "tone" soon!
