    Can someone tell me what would be the difference between a bass that has a 12" (305mm) Radius vs. a 9.5" (241mm) radius? How about the difference between fender medium jumbo frets and vintage style frets? Thanks!

    Imagine you chopped the neck in half. Look at the surface of the fretboard - it forms a curve, an arc, which is a portion of a circle. The distance from the fingerboard surface to the center of the circle is the fretboard radius. If the center of the circle is close, it is a small radius, and the arc is rather curved. This is like a traditional Fender 9.5" radius. If the center is farther away, the arc is flatter, and has a higher radius measurement. If the center were infinitely distant, the fingerboard would be flat, with no radius, like a bajo, or a few basses.

    A good place to see the fret sizes is on the Warmoth site.

    Thanks pilotjones,
    So let me get this straight. That means that a bass with a 12" radius will have a flatter fretboard than one with a 9.5" radius. Is that right?

    You are correct, sir.

    BTW, the best radius ever was 7.25, I've got bar graphs and flowery adjectives to prove it.
