I really do not know how to answer that. If a partscaster is any guitar that has a part on it that is not factory installed, then yes, I guess it's a partscaster. But there is a "gray" area here where lots of folks change out pickups, necks, bridges, etc. for the purpose of upgrading, yet continue to call the guitar "original but upgraded". I don't know where the line is drawn and really do not give it much thought. Every guitar I have built has used all Genuine Fender parts (usually new) or significantly upgraded parts like SD pickups, Callaham bridges, etc. Partscaster (to me) sends a very bad message about guitars made up of old, junk parts, but if the "rules" makes any change to a guitar, good or bad, a partscaster it really makes very little difference to me.
