Wow thats some good info to know! I gather my 'Haggard P' was right at the tail end of 'quality' before this meltdown?
I think as with all 70s Fenders, the term is "your mileage may vary," but definitely early 1980s were even more so hit and miss. Parts were not a major investment target for Fender in those years, and some instruments had parts from earlier eras - I believe I saw one picture of a late 70s - early 80s P bass that even had a stock three bolt neck plate, like the earlier 70s Jazz basses.
I agree, to the OP, with Dr. Jim - for the money, get an '08. It may be "worth" 60% of the new price when you get it home, but that's better than having an unplayable bass for the same price, and the 08 will hold its value over future years just like the 81 has. Or buy an 08 used if you can find one. Mine is black and maple too, and I slapped a black pickguard on it, so it looks just as cool, except I can play the crap out of it for decades to come.
