The Guild "Anti-Hum" small humbucking pickup was used on most Guild electric guitars from 1963 to 1970
as well as on some of the Korean-made reissue models. Notice the unique construction where one coil has
small adjustable pole pieces and the other coil has a blade pole piece like those found on Gretsch Super'Tron
pickups. The adjustable poles only have a subtle effect on the tone and volume when raised or lowered.
