I played a bunch of good guitars when I was at the
vintage shop where I found my 57 Country Western.
There's a Santa Cruz there with a fretboard radius
that seems totally flat... I didn't measure it, but when
I picked it up to try it out, I put it right back down.
My only guitar for the last 18 years or so is a
luthier made guitar from Utah... I've kind of gone
crazy the last few months and now I have a
53 cf-100 and a 57 Country Western. Right away
I started wondering how to characterize the ways their
necks are different in some kind of objective way. I got this
cheap little tool (less than $10) that lets you
measure neck radius...
