I just bought a 1981 Peavey T-40 that had an intermittent problem with the neck pickup cutting out. After some diagnostics it turns out that there is a bad connection inside of the pickup, these pickups being unrepairable, and no with no new replacements available, used is my only option. Which leads me to question #1 Mine is an 81 there are 3 on ebay right now, all are from 79. What is the difference tonally, and output wise, from the earlier ones with out the exposed blades compared to the later ones, like I have, with the exposed blades. I'm not that concerned in with the visual differences between the two. Question #2 is, Are the neck and bridge pickups the same pickup, or is the bridge wound hotter than the neck like in some cases. If anyone has a pickup they would like to get rid, of please let me know. I would rather replace it with the same pickup with the exposed blade if at all possible.
