This is a set of pickups that came in a P bass that I bought in the late 70's. I'm pretty sure they are DiMarzio but not positive - there is no logo or wording on the pickups. At that time, Dimarzio was just starting to come out with replacement pickups for bass, which is why I think they are dimarzio. There are stickers on the bottom of the pickups that say "Patent Applied For".
The switch allows you to get two sounds, one is the typical P-Bass tone, and the other one is thinner, with less midrange, more of a hi-fi sound.
I replaced these in my P bass with the Duncan Quarter Pounder, which is why they are in the Duncan packaging, but these are definitely NOT duncan pickups.
I'll take $15 including USPS shipping for these pickups. Paypal or MO.
