I bought a set from Ludlow Street Guitars back in '99. I still say they are my favorite Stratocaster pickups. He seems to be the only builder making grey bottom pickups with the correct wire for 1965-66. Everyone else insist on using the darker stuff used in the later 60's. It's optics mostly but looks matter even if you can't see them.
Oh yeah, how do they sound? He gets one thing wrong. The bridge pickup is about 7.48k. I've never seen an original Fender pickup that high in a Strat. But it's the kind of wrong I like. I need a macho bridge pickup that ventures into humbucker territory. Less high end, more low mids. All I can say is I threw these in and my guitar which was kind of inspiring came to life. Now it's really inspiring!
Bought these on EBay from "tHe aMp sHOp" in Los Angeles. Great spot. I know it well. Cost was $245 shipped. I don't think I could do better than this. I love them! Worth a go for your mid 60's Stratocaster clone. Big tone like it should be.
