I started out ten years or so ago, to try to determine how essential the neck was, to the sound of each and every guitar I finished and assembled. At first I was a rebel, putting rosewood board necks on ash body guitars and all maple necks on mahogany and alder bodied guitars. And I found some great sonic matches and necks and bodies that fit together great and all that. But the thing was, I guess I like the LOOK of maple with ash and the LOOK of rosewood with alder or mahogany. The Design Language of the guitar. If I had a figured maple top on a guitar, the rosewood board neck just looked "right". And the ash looked right with the trans finished one piece ash bodies. Now, the other way around they looked "cool" but when done in the pattern that St. Leo already set up, they just seemed to look "right" and when people heard them played, they listened with their eyes and their eyes liked what they "heard". What can I say? I gave up over time, on being the rebel so much.
