I just picked up this P-bass this morning. No idea how old it is or what year it is (but I have my guesses and am keeping my fingers crossed. I'm not a bass player (banjo, guitar, ukulele) and was looking for a cheap MIM to throw a Badass bridge and Fralin pup in, and came across this one... Obviously the Badass bridge isn't stock, and neither is the Dimarzio pup. The serial number dates it to around 1975, and has the "f" on the neck plate which was done around this time if I understand it correctly. I have attached pics of the neck but unfortunately cannot identify the stamp on it. I've also attached pics of the neck joint, since maybe someone could identify the stamps/markings in there. The pots have the numbers: 032367, 1377613, 250K-A on them. So what's the consensus? I paid $250 for this P-bass and a Crate BX-40 amp.
