I've always liked the Warmoth Compound Radius, but I find 16" a bit too flat at the upper region... It would be nice if they offered a less dramatic compound such as 7 1/4"- 9.5" or 9.5"- 12" . USACG does it & it's very popular.
I guess those would be nice, but why do you find 16" too extreme up there? You're not usually doing a lot of full bar chords way up on the 19th fret anyhow, are you? I don't see the advantage to a small radius in the higher frets. 9.5-12 might be nice I guess.
i'd like to see how a compound radius is done. i'm sure producing a diferent one wouldn't bee an easy task, and i agree with gregg, err somewhat. the diference between 7" and 9" is more notable than say maybe 9 and 12 and probably even 10 to 16 but really i can't think of an advantage over a straight radius. it's still not flat enough to help your bends a whole lot. i'm all for more options but is the money/effort worth the results? how many people will actually order it?
