Probably better places to try to move this, but i'll give it a try. Picked up a late 70s Yamaha Studio Lord , as a project, awhile back. It had this pickup and a Super Distortion. The guitar is turning out to be more of a project than expected, so looking to recoup some of my funds. Honestly don't know a lot about the pickup. I would guess it is late 70s to early 8os. Any help with identification would be welcome.
