Re: saddle radius
Don'y buy some stupid tool dude that you'll only use once, get a cheap steel engineers rule.
I've got a Sil Special myself, this is how i set up mine.
I don't like a bridge to sit flush, so i raised the front edge slightly so that when I dip the trem it doesn't touch the body and I then tilted the back edge forward slightly.
I only use the trem for slurs and occasional vibrato, never extreme stuff.
THEN, measure the string height at the 12th fret ( top of fret to underneath the string ) and raise the saddle until you get the ideal height.
Do this on every string and when done, they'll perfectly follow the radius.
Once they're all done, sight along the neck to make sure the saddles are parallel to the bridge plate.
Takes a little patience to get it right but it only needs doing once, so it's worth it.
