My Gibson Memphis 339 Studio is also all maple -- maple body, maple center block, maple neck with baked maple fretboard, also with 57 Classics.
It's a little scary how dark and throaty the guitar is. Not really "bright" at all, which surprises me.
Switch to the neck pickup and turn the neck tone down a bit, and it's all smoky jazz club and Clapton woman tone. I put my 339 down, and my clothes smell like I've been smoking. :nervous:
Maple is still very much a traditional guitar tone wood, even for Gibson.
