The first humbucker was the P.A.F. by Seth Lover (the PAF got its name because the "patent applied for" sticker was still stuck on the underside). It became a hallmark of classic Gibson guitars, appearing in iconic models like the Les Paul, SG, and ES series, as well as in more unconventional designs such as the Flying V and Explorer. For many players, the P.A.F. remains unmatched—never harsh or overbearing, but rich, nuanced, and capable of delivering a uniquely expressive tone. These days, even players known for heavier tones often choose a PAF for the neck position, thanks to how well its smooth, balanced character complements a more aggressive-sounding pickup at the bridge.
