with the serial number? it's a 2003 mia p, sunburst w/rosewood. next to some pictures it looks like ash, some it looks alder. it's a two piece body. serial number z4038031.
I dunno HOW you'd find out by looking at Fender.com etc or online. Maybe someone who owns one-same model etc can help. Otherwise if U can find a bit of "naked" wood- (in the neck pocket for example - if U take the neck off) - AFAIK Ash has a much LIGHTER coloring-almost "blonde", where as ALDER is a darker "light BROWN" type color.
