i'm with Philly at the minute on the Mahogany body, set mahogany neck, rosewood board. it just works. i always liked Les Pauls, but now i find my SG, Melody Maker and Flying V are just more alive, more resonant.
curiously though, my all time favourite guitar, that i always end up returning to, has a Poplar body and a set Maple neck, with Maple board. i do love the snap of maple fretboards. i've had a couple of guitars with ebony boards, and i've never really got on with it. it doesn't have the warmth of rosewood or the snap of maple. it somehow sounds kind of plasticky to my ears. i'm in the minority, but i don't really like the look of it either.
