Clean Skin (4.87k)Great for guitars with a neck humbucker and bridge single coil, like the recent model Fender Telecaster and others.  Thanks to Kinman’s Triple Alnico Tone advantage it has a juicy single coil vibe (think fatter P-90 sound) which makes it great for the neck position because it overcomes the tendency of conventional humbuckers to be wooffy &amp; mushy with reduced definition of low notes at high volume.

PAF + (7.5k)A much improved PAF which works better in the neck position than conventional humbuckers and is excellent for the bridge position. Featuring vastly improved Tone / definition / clarity on the wound strings with minimium blurring from the low notes in the neck position, thanks to Kinman’s Triple Alnico Tone advantage.  Compared to a vintage PAF humbucker it has better attack, touch sensitivity and dynamic response and tracks as fast as lightening in response to blurringly fast pick attack and is very responsive to pinch harmonics and hammer-ons which makes it a must for shredders. The bridge position growls effortlessly on the wound strings and sings sweetly on the plain strings with an intense harmonic bloom which is not spiky. The neck position has well defined and clear low notes that have a strong hint of twang and more than a good dose of piano tones in the mids. Split single coil sound is very very nice, very P-90 like.More info here
