Anyone know what these are?

That would appear to be a signature, not just initials.

Yeah looks that way. Same thing; the mark of the maker.

Looks like the first letter is a D?

FWIW I've seen reference to "Wizz" pickups, and apparently they are "Croatian hand made (in Koprivnica)" PUs. Don't know (don't really care much) about them, but this is what comes up searching (using partly Japanese in google) :

I knew I'd seen them somewhere before.

I suppose I should share what I know about Whizz pickups but none of it's good and no one here will be too interested to hear about it.

I think some of the guys got things the wrong way. The OP said that he istalled the Wizz pickups and that he got to keep the pickups that he swapped out.

I installed some Wizz pickups in a customers guitar and said i could have these. any idea what they are? Thanks

Or?
