Hmmm, maybe I should ask someone to x-ray it one day ... but actually don't care. It's very well balanced , love the feel and the tone, I don't need more weight in a guitar body, I already have enough of it in mine :roll:
Its easy to find out if you tap on the guitar body it should sound hollow at some places, just like how it sounds when tapping on the back where the pickups are.
I have read that the Edwards are made solid, but with a light mahagony (not to be confused with Korina which is a different kind mahagony) and a hard maple top(a louder clearer kind of tonewood) like most MIJ LP's are. This combo works very well for any not-too-midrangy music like rock for instance. Density(heavier) amplifies the characteristics of the wood a bit. A light mahagony body with a hard(dense) maple top will have more of a clear, fairly loud tone when compared to a heavy gibson LP.
There is some mahagony which has the rather exclusive 'sparkle' to the tone of the wood but after gain and effects i doubt most would hear that difference.
I personally have a bit of a fetish with these kind of things, all the different types of woods add something to the acoustic tone color. The combination of strings, pickup and wood, if picked in with a synergetic or even holistic approach can just be mindblowing. Learning to understand the complexity of tone and all its characteristics and properties can really enhance your sound IMO.
