What is sonically unique about the Whole Lotta Humbucker pickups is the way that they push your amp and add a very slight natural compression and sustain to your playing
Imagine taking the Vintage models and turning up the output. You get a fat and full punch in both the low frequencies and mid-range, yet it retains the muscular twang of the Vintage.
Imagine the pickups out of an old '52 gold top or a '59 ES-330. By removing the cover you´ll find the same hand-fabricated bobbins, wire and "flatback" tape that was used in the originals
