Hello, I'm considering picking up a classic 59 pickup from someone, how can I tell that this is the real thing and not a copy (As this is a purchase, and I've been burned before)??? The bottom of the pickup has no identifying markings, and the lead wire coming from it is covered in gray cloth. (The interweb has been less than helpful :S). The shape of the pickup tabs where they screw into look identical to that of the Gibson. Heres a pic, the top one should be a dimarzio dp100 too correct?
