whats the difference between maple and rosewood fretboards? how does it effect the playing?
it really doesn't affect the playing so much as the tone. A maple fretboard will allow every blemish and uniqueness in every note be heard. It will also have a very bright sound. if It is is a finished neck, then it will be sticky unless you keep good care of it.

Rosewood will be less bright and will have a smoother, warmer tone.

Personally, i like maple.

Ebony is another great wood for fretboards. It has a bright, yet also warm, smooth feel. It is also very cool looking, with a dark, rich color, as opposed to the lighter, browner rosewood.
its all personal preferance, im perosnally an all rosewood player. theres also ebony and a couple other lesser used woods.
