The P-90 (sometimes written P90) 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. Compared to other single coil designs, such as the ubiquitous Fender single coil, the bobbin for a P-90 is wider but shorter. The Fender style single coil is wound in a taller bobbin but the wires are closer to the individual poles. This makes the P-90 produce a different type of tone, somewhat warmer with less edge and brightness. As with other single-coil pickups, the P-90 is subject to mains hum unless some form of hum cancelling is used.
