This is a NOS Schaller 10/404 bass humbucker pickup in black. It features adjustable slotted pole pieces, a mounting ring/bezel, and leads w/ an 1/8" jack attached! No soldering! I didn't realize this already had a jack on it when I purchased it, so my blunder is your lucky day!
Unfortunately, this does not come w/ any of the original paperwork. It is meant for narrower string spacing, approximately 5/8" pole center to pole center.
$35
