I used these in my old P Bass while I got the original pickups overhauled. To be perfectly honest, they sound pretty much as good as the originals - they have a lovely warm thump as you'd expect. They were only in there for about 2 months and have just sat on a shelf ever since. 

Officially they are used and have obviously been (carefully) soldered in and out again. (I'm pretty certain I have the 4 screws too - if I can find them, I will throw them in)

Hopefully somebody can get some use from these lovely pickups.

Amy questions, please shout.
