The P-90 is a single coil electric guitar pickup produced by Gibson since 1946. Gibson is still producing P-90s, and there are outside companies that manufacture replacement versions.

History

Around 1940 Gibson offered a new bridge pickup for ES-100/125 series, as an alternative to the classic Charlie Christian, cased in metal.

Officially P-90 pickups were introduced in 1946, when Gibson resumed guitar production after World War II. They were initially used to replace Gibson's original "bar" or "blade" pickup (also known by many 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.

The P-90's reign as the Gibson standard pickup was short-lived, however, as a new design of pickup, the humbucker, was introduced in 1957. Equipped with double coils, the new pickup boasted greater output and less hum, although with less high end response. 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. This trend continued throughout the 1960s and particularly in the early 1970s, where the pickup all but disappeared from the entire Gibson range. 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.

The FN P90 is a personal defense weapon (PDW) designed and manufactured by FN Herstal in Belgium. Created in response to NATO requests for a replacement for 9×19mm Parabellum firearms, the P90 was designed as a compact but powerful firearm for vehicle crews, operators of crew-served weapons, support personnel, special forces and counter-terrorist groups.

Designed by FN in conjunction with the FN Five-seven pistol and FN 5.7×28mm ammunition, development of the weapon began in 1986, and production commenced in 1990 (from which the "90" in its name is derived), whereupon the 5.7×28mm ammunition was redesigned and shortened. A modified version of the P90 with a magazine adapted to use the new ammunition was introduced in 1993, and the Five-seven pistol was subsequently introduced as a companion weapon using the same 5.7×28mm ammunition.

Featuring a compact bullpup design with an integrated reflex sight and fully ambidextrous controls, the P90 is an unconventional weapon with a futuristic appearance. Its design incorporates several innovations such as a unique top-mounted magazine and FN's small-caliber, high-velocity 5.7×28mm ammunition.
