Hi, I've found a P Bass that if it really is a MIJ might be a good deal. He says the neck is very nice. Straight, truss rod works fine, frets are in good shape. Body has minimal scratches on it. It has a vintage BadAss II bridge and brand new Fender American tuners w/ a Hipshot D-tuner, vintage pic guard. He was told by the previous owner it is a CIJ but there are no visible serial numbers. The pic's I've got are not very good, so I can't tell a lot of detail. Is there any tell tale sign of it being a real Japan P without taking the bass apart? He's nervous about doing this, isn't very handy and doesn't want to take the risk. He said had it set up by a luthier when he bought it and it plays great, doesn't want to screw that up. Based on the knowledge it may not be a real CIJ, what do you think its worth? Thanks for your help!
