Most electric bass guitars use magnetic pickups. The vibrations of the instrument's ferrous metal strings within the magnetic field of the permanent magnets in magnetic pickups produce small variations in the magnetic flux threading the coils of the pickups. This in turn produces small electrical voltages in the coils. Many bass players connect the signal from the bass guitar's pickups to a bass amplifier and loudspeaker using a 1/4" patch cord. These low-level signals are then strengthened by the bass amp's preamplifier electronic circuits, and then amplified with the bass amp's power amplifier and played through one or more speaker(s) in a cabinet.
The late Bernard Edwards, bass player with the Disco group Chic, was known to use a technique called chucking to pluck the bass strings with the forefinger of his right hand, in a manner similar to how strings are plucked with a plectrum.[not in citation given] Chucking uses the soft part of the forefinger and the nail of the forefinger to alternately strike the string in an up-down manner. The thumb supports the forefinger at the first joint, as though using an invisible plectrum. With a flexible wrist action, chucking facilitates rapid rhythmic sequences of notes played on different strings, particular notes that are an octave apart. Chucking is distinguished from plucking in that the attack is softer with a sound closer to that produced by the use of fingers. Chucking allows a mix of plucking and finger techniques on a given song, without having to take up or put down a plectrum. Examples of Edwards’ use of chucking on his Music Man Stingray bass can be heard on the intro and solo section of "Everybody Dance" and the foundation bass line of "Dance Dance Dance".
Since there are so many digital pianos worthy of your attention in this catalog, you may want to narrow down your choices using some of the search options on the sidebar. For example, if you select stage digital pianos under the category section, you'll be presented with all the digital pianos that were made for the stage. Once here you have the opportunity to drill down even further and can search by topics like number of keys, MIDI/USB Connections or by whether or not the digital piano has built-in speakers.
