So I was flicking through the guitar magazines in 'Smiths when I take a look at the engraved pickups adorning this custom guitar in the first article, and each read: "Organic BKP". I skim-read on, with a little box claiming they're vintage hot and sound organic. Hmm...so what are they, and are they only available on that guitar (sorry - can't remember the name - it was a furiously quick browse)?
Cheers!
