The recipe for these pickups starts with a rough cast Alnico 5 magnet, plain enamel wire, and Seymour's unique wind pattern. The bridge is a hotter-than-vintage 8.78k DC resistance and the neck is similarly beefy at 8.20k. Tonally, the rough cast magnets add warmth and balanced note-to-note clarity so everything sounds bigger. 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.
