from what i could see they are the stock floyd rose pickups. this guys site is
www.wyreriverguitars.co.uk, it's a real basic site but it's got his contact details on it.
can i ask you guys a question? what other sort of headstock shape would look good on the end of richie's white FR? ya see i'm having second thoughts about the les paul style, i'm thinking maybe a prs style? would love the Fr style but don't wanna get sued!
