Hi, Cedric01.
Believe it or not, I still haven't read Fretboard Logic, I've only seen snippets of it, so I can't really comment. I guess that any fretboard mapping system has to refer in some way or other to the
CAGED template, since that is the way music and the fretboard come together. The editor of GuitarNoise.com, Nick Torres, who obviously has read Fretboard Logic, said
PlaneTalk makes it look like brain surgery by comparison ... pretty much the same as allthumbs says.
Bottom line, though, there is only one fretboard layout ... but many ways of explaining it. From the feedback I've been getting ever since I started teaching it, that's where
PT excels.
I must make a point of ordering Fretboard Logic!!
