In 1968, Gibson reissued the original, single-cutaway Les Paul, one version being a Goldtop with P-90 pickups. By the 1970s, smaller single-coil pickups, mini-humbucking pickups, and uncovered humbucking pickups began replacing the P-90 pickups on Gibson's budget and lower-end models. This trend continued throughout the 1960s and particularly in the early 1970s, where the P-90 all but disappeared from the entire Gibson range. This new pickup, occasionally named PAF, very quickly took over as the preferred choice for all Gibson models, relegating the P-90 to budget models such as the ES-330, the Les Paul Junior and Special, and the SG Junior and Special, such as those used by Pete Townshend and Carlos Santana. Equipped with double coils, the new pickup boasted greater output and less hum, although with less high end response. The P-90's reign as the Gibson standard pickup was short-lived, as a new design of pickup, the humbucker, was introduced in 1957. They were initially used to replace Gibson's original "bar" or "blade" pickup, also known as the Charlie Christian pickup, on models such as the ES-150, and by the end of the 1940s it was the standard pickup on all models. Officially, P-90 pickups were introduced in 1946, when Gibson resumed guitar production after World War 2.
