I just came across this video and thought it was interesting. "Similar" types of wood. I don't know how similarly the pickup heights were set. However, I can definitely hear the difference with headphones. It could be the age of the trees that generated the wood, the nitro finish, maybe the more attention to detail or a combination of several factor that account for the differences. With that said, both sounded great, but in my opinion the PS had an edge. This is coming from someone that until fairly recently didn't think there was a significant improvement going from a Core to a PS other than the option of exotic or non-standard timbers. This wasn't at all the sort of difference I expected.
