The Extra Vintage model has even more vintage flavor than a PAF. The 30% under-wound Extra Vintage has sweeter highs and more detailed midrange tone than regular Vintage or PAF humbuckers thanks to the Triple Alnico Tone advantage. Has some of the thwack factor of a P-90 thanks to improved attack. Midrange honk has been reduced so the sound is remarkably fresh and open. It is also noticeably more touch sensitive and responsive.
It's a cleaner sound on the wound strings (less growl) in the bridge position and sings sweetly on the plain strings with a nice harmonic bloom. The plain strings never sound offensive / harsh like they often do with conventional humbuckers. High end harmonic clarity shines through heavy distortion which is not the case with conventional humbuckers.
Works better than conventional humbuckers in the neck position because of minimized woof and mush factor and is also good for the Bridge position. A pair of Extra Vintage is highly recommended for Arch-top Jazz guitars since they produces a nice, sweet both-on-together sound and the bridge has a low growl factor.
