There are a few sites around that describe the affects different wood types have in different positions. For example, an all-maple neck tends to give a brighter tone than having an ebony or rosewood fretboard. Alder is the most common compromise between bright- and dark-sounding wood for a Strat body, and is the type used on most Fender American Strats. Mahogany is darker, basswood is usually darker, ash is brighter...
Ah, I see that Warmoth has a nice
page that describes all of the wood types including their affects on tone.
