They're actually asymmetrical C shaped in profile, which slightly thinner on the bass side and is what Takamine uses. I have a Martin, Gallagher, Guild, and have played dozens of others but I play this Takamine in our Praise Band at church every Sunday (it's the only one with electronics so that's one reason). I have grown to really love this neck shape so that's what I'm using for my build.Did you create elliptical curves or partial arcs? Are you planning on carving the guitar neck by hand or CNC carving it? I like the idea of matching the profile to a guitar you enjoy playing. My wife plays, but is very picky about the width and depth of the neck of her guitars. It seems the only one she really thinks “fits” her is a $2500 Taylor 12 string.
No, Tim, I decided not to do a build because I knew it was going to take a long time. When I finish I'll post some photos, probably in detail, but no build thread.i am looking forward to try using the cnc to make fret scale/indexers for the table saw out of plexi. are you threading the build somewhere?
