New to me SBMM Valentine but question on pickups

I just joined your merry band (although my son has had a stingray fretless 5 for the past 6 years, so perhaps I have been an EBMM owner for a while as I funded his purchase).

I have been wanting an EBMM Valentine for a bit but with a kid in college and one in daycare my disposable income has been, well, disposed of. So I picked up a SBMM Valentine yesterday. The original owner did some nice things to make it a player (new tone pot for a Q sound, refinished neck after sanding, level a couple frets, and strap locks).

My question is; what is the material in the pickups? Are they ceramic or alnico?

Thanks all!
