Ok, I've done a fair bit of surfing the web about gold foil pickups. First of all, I was right about the DeArmond moustache pickups in my old Harmony Silhouette being gold foils. I remember that guitar fondly, but it's been decades since I've played it/heard them. And back in the day I had a cheap practice amp, which doesn't help matters. And I was right, they were single coils, kind of a P-90 size. From what I found online, AllParts and Lollar make gold foils, and they are single coils as well. Is there such a thing as a gold foil humbucker? Does anyone else make gold foils?
