Rick is another genius, IMO. I read that whole article and he talks about the diff in sound between an all mahogany guitar and one with an arched maple top. And the interaction between maple and mahogany.
Also the diff in tone from having a solid body guitar with an arched top vs. a flat top.
Rick's Model One has an arched back as well as an arched top, and he feels that the wood vibrates more nicely, even in a solid body, if the top and back are not parallel surfaces.
Rick was one of the founders of Alembic, he and Stanley Owsley (the acid test chemist and genius) built the Wall Of Sound Grateful Dead PA together, and he created the Turner Model One guitar with the rotating humbucking pickup you see Lindsey Buckingham always playing.
Before that, Buckingham played Strats and Les Pauls. Stopped using them almost completely after Rick gave him the Model One prototype before a show. Buckingham used it that night for the whole Fleetwood Mac show.
Buckingham also plays the Turner Renaissance acoustic/electric guitars. Those are pretty fabulous too!
