I really love the sound of PAF-style humbuckers with alnico ll magnets. I love the medium output and their warm, fat, and smooth, yet bright and well-defined tone. To me, the '57 PAF sound is precisely what I want in a vintage style HB. Great for just about anything except metal. My personal favorite is the Seymour Duncan Seth Lover set. I wouldn't change a thing about them. Exactly what I was looking for; and they sound so good with my ver.4 OCD. And even though they're not wax-potted, I don't have any noise or microphonic issues (and I think the very slight bit of honkyness is an important part of it's character. What's your favorite? And what do you love about them?
