I have a Mexican P Bass from around 2006-2007 s/n. What kind of wood is it made from? I have put Seymour Duncan Antiquity II's in it, a Hipshot bridge, and Hipshot Tuners. Was a it a waste to mod a Mexican guitar this much rather than start with an American made model? Are the Americans made from better wood? Do they have better finishes? What are some honest opinions?
