Got a P bass recently, and the seller said it was all original except the pickup, which had been replaced (apparently a looooong time ago) with a DiMarzio Model P. The bass is prolly a '78, and the pickups may be about the same vintage, since they had the Patent Applied For sticker. So anyway, I had heard that the Model P might be a bit brash or aggressive for those who like the "regular" P tone. Not so, at least in this case. Sounds very P-ish in fact. Pretty loud, but still has those nifty mids I expect from a Precision. I figured that when I got the bass, I might change it out for a Fender Original '62, an Antiquity, or the like, but now that I've played it, I have no such plans.
