I've personally found maple (and koa) to be the most polarizing of wood choices: people love it or don't much care for it.
I'm in the former camp, but just like any wood, it's gotta sound "right" with the guitar in your hands as koa and maple are the two woods I would
never buy without playing
first, whereas I would (and have) rolled the dice on many other woods and have been find, IMHO.
So to your question, what I love about maple is it is a
forward-sounding wood, offering fast/snappy attack, and a tonal "presence" that is so very clear and deliberate; likewise a strong midrange that never allows the tone to get "buried" or lost. It's that fundamental tone's dominance and the lesser harmonic overtones that I find alluring, while others feel its lack of overtones is a deficit. And keep in mind many seem to call maple "bright" or "thin" ...this can be true with some guitars, but IMHO is too often over-applied as some mistake that emphasis on the fundamental as thin sounding when, in fact, it's big-toned but decaying faster than with a guitar replete with overtones.
So many variables with maple (not unlike other guitars, really), so like any voice, it's best you hear/play for yourself. FWIW, I
used to think maple sounded best on big-bodied guitars, then I fell into the most glorious-sounding GC-sized maple that debunked that misconception in a heartbeat. This "little" body has big and round bass notes, a thick/defined midrange that clearly stands forward, yet overall is not what anyone would consider bright as it has a very crisp top end with clear "outline" around the notes, but is never jangly. Heck, it seems even the trebles have girth to it (yes, I bought it
). And yes, mine would be stellar for fingerstyle. So don't let the generalizations or "conventional wisdom" sway you: the maple guitar in your hands either does it for you or misses. Hope that gives you something to think about
