The Fender Precision Bass (often shortened to "P Bass") is an electric bass guitar. Designed by Leo Fender and brought to market in 1951, the Precision Bass was the first bass guitar to earn widespread attention and use. A revolutionary instrument for the time, the Precision Bass has made an immeasurable impact on the sound of popular music of the last 60 years.

In its stock configuration, the Precision Bass is an alder or ash-bodied solid body instrument equipped with a single split-coil humbucking pickup and a one-piece maple neck with rosewood or maple fingerboard and 20 frets. To this day, the Precision Bass is among the best-selling electric basses of all time.
