Hey, I have changed pickups in a few guitars of mine and some friends and the discarded ones don't get used again so theyre just gathering dust.

These would be ideal for budget builds

Consists of:
Three Squier pickups, two with white covers one with black
2 unknown pickups with black covers and staggered polepieces

theres a few springs and screws in the bag too, i thinks theres enough for all of them to be fitted but if not they just use regular hardware store screws.

Dirt Cheap!
ive got tonnes of strat pickups lying around too, eventually i want to wire them all together to make some monstrosity-bucker

i heard you can make a good bullet mic out of a strat pickup and a tin can

and the neck pickups soldered to a jack make great acoustic pickups too, dead warm
