ThroBak KZ-115 PAF humbucker reproductions represent the tonal dawn of the PAF pickups era with an accuracy that can only be matched if you took a time machine back to the Gibson Kalamazoo factory in 1957. Wound on the very KZ/LP-115 winding machine Gibson used for both PAF humbuckers and P90 pickups in 1957 and rescued from Kalamazoo by none other than Les Paul himself before Gibson's move to Nashville. ThroBak KZ-115 PAF pickups awaken the elusive early PAF pickup dynamics and low end depth of the originals. The KZ-115 owes its distinct tone to the custom Gibson Kalamazoo winding fixtures, wire guides and set-up of the original vintage winder. The original, non adjustable, 1950's lobeless cam traverse and limiting fixtures, wind what we call the KZ-115 vintage center focused coil. These center focused coils create a fuller bobbin for the same number of turns than coils wound on the other known PAF winders, the Leesona 102, Slug 101 and ME-301. The result is a PAF pickup reproduction with added scatter for a woolly low end and crispy/crunchy mids. ThroBak KZ-115 proves again that the machines matter when it comes to vintage PAF accuracy!
