Compund radius ?

[Dreamsinger]

By my reasoning compound radii are unnecessary on basses. My Yamaha 5 is around 20" radius all the way.

What kind of bridge are you looking for?
I shimmed rhe Floyd Rose saddles on my Warmoth Soloist with 10"-16" compound radius.
Radius is a non-issue with adjustable string saddles.
