Just wondering if anyone has changed the pickups in one of the JP models? If so, what did you replace them with, and how did you find it? Also, did you have to rout the guitar or make any modifications to get the new pickups to fit? I have been looking at replacing the pickups in my JP15 but it looks like nothing else will fit in there apart from the stock pickups (well, nothing in the boutique/scatter wound/hand wound end of the market). Any ideas or comments hugely appreciated. Big thanks!
