i might get a fender strat so should i get the maple or rosewood fretboard?whats the difference in sound?
Get what you feel comfortable with and like the sound of best, if you don't know, you shouldn't be considering getting one!

Rosewood = warmer
Maple = twangier, brighter

Of the two, I prefer maple, but it depends on which you personally like the best, quite obviously.
There's only one thing we can do to thwart the plot of these albino shape-shifting lizard BITCHES!
Play both, see what you like the most - I prefer maple - which I have on my MIA Tele, but the rosewood fretboard on my strat is lovely too.

I couldn't really find a HUGE difference from the fretboards soundwise when I was trying out Telecasters, but there is a fairly significant difference in feel IMO.
i love the look and feel of a maple neck. you should try them both and see which one you prefer.
