In addition to pressing down one note at a time, bassists can also press down several notes at one time with their fretting hand to perform a double stop (two notes at once) or a chord. While double stops and chords are used less often by bassists than by electric guitarists playing rhythm guitar, a variety of double stops and chords can be performed on the electric bass. Some double stops used by bassists include octaves. Chords can be especially with effective on instruments with higher ranges such as six-string basses. Another variation to fully pressing down a string is to gently graze the string with the finger at the harmonic node points on the string, which creates chime-like upper partials (also called "overtones"). Glissando is an effect in which the fretting hand slides up or down the neck, which can be used to create a slide in pitch up or down. A subtle glissando can be performed by moving the fretting hand without plucking or picking the string; for a more pronounced effect, the string is plucked or picked first, or, in a metal or hardcore punk context, a pick may be scraped along the sides of the lower strings.
"Jazz" pickups (referring to the original Fender Jazz Bass), also referred to as "J pickups", are wider eight-pole pickups that lie underneath all four strings. J pickups are typically single-coil designs, though there are a large number of humbucking designs. Traditionally, two of them are used, one of them near the bridge and another closer to the neck. As with the halves of P-pickups, the J-pickups are reverse-wound with reverse magnetic polarity. As a result, they have hum canceling properties when used at the same volume, with hum cancellation decreasing when the pickups are at unequal volume, and absent if the player uses only one pickup. 'J' Style pickups tend to have a lower output and a thinner sound than 'P' Style pickups. Many bassists combine a 'J' pickup at the bridge and a 'P' pickup at the neck, so they can blend the two sounds.
