When Phil Jacoby at philtone.com built my Tiger-inspired
one-off Philtone Jerrycaster we'd designed together (pictured below), he showed me the body before adding the cocobol top and back. He'd routed out a fair amount of wood from the exceptionally heavy and dense mahogany center we chose together but his routs were both randomly placed and of varying diameters.
I wish I still had a picture of how they were placed to share with you now but I can tell you that Phil emphasized to me from his deep personal luthiery experience that the key to weight-reliefing a body while avoiding turning the guitar's tone from a solid body into a semihollow is to do it this way.
I love the way my guitar came out, it plays and sounds so good. Some will tell you it's impossible to use a mahogany body and have the final product sound Jerry-like. In my case, all I can say is the combination of my super-stiff sapele (that looks like mahogany but has a quotient of elasticity closer to maple's)-maple-padouk-maple-sapele 5-piece neck with its ebony board and cocobolo top give me incredible immediacy and snap with a strong fundamental tone.
Where the mahogany center may come into play more is in how the notes decay. I hear a bit more warmth in my guitar's decay than in my Scarlet Fire Wolf's which is what I was seeking for this specific guitar (my range of music features Dead and JGB but isn't limited to it).
This is more info. than you requested but what can I say - I've got some extra time these days.
