Yep, I've become a fan of Mahogany too, particularly since putting together an all Mahogany "strat" (Rosewood fingerboard). I went with a durable oil finish instead of the traditional thick lacquer or poly finish. The resonation through the wood including the body and the sound even acoustically is just ridiculous.
High grade Mahogany without question for me, they just have the natural tone and resonance pleasurabe to my ears
I have built plenty or parts monsters in various body woods and Mahogany tops the list, followed by Swamp Ash and then Ash...alder, basswood and solid maple bottom of my list. All maple is cool when you find the right pickup to use with it but it canbe tricky.
I'm convinced >75% of tone comes from the neck (as far as the body/neck woods are concerned). I prefer birdseye maple necks FWIW. As far as bodies, I like strats in ash usually.
Found out that my G&L is most likely maple body through some research and discussions on the GL forum. If that's the case, then I really dig maple bodied guitars!
No real preference for an electric guitar here, since wood isn't as big of a tonal component as we like to think it is. As long as it's not super heavy, I'm happy.
