Some basses, particularly expensive boutique instruments or custom-made guitars, use more unusual pickup configurations. Examples include a soapbar and a "P" pickup (found on some Fender basses), bassist Stu Hamm's "Urge" basses, which have a "P" pickup sandwiched between two "J" pickups, and some of funk bassist Bootsy Collins' custom basses, which had as many as five J pickups. Another unusual pickup configuration is found on some of the custom basses that virtuoso bassist Billy Sheehan uses, in which there is one humbucker at the neck and a split-coil pickup at the middle position.
A midi controller does not have any sounds of its own. It requires a virtual instrument (as a trigger) to produce sounds. So, if you get an acoustic piano virtual instrument, your midi controller will be an acoustic piano. If your virtual instrument is a drum, violin, electric piano etc., your midi controller will be exactly those instruments because it takes its tone from the virtual instrument.
In other less mainstream genres, such as hardcore punk or metal, the pedagogical systems and training sequences are typically not formalized and institutionalized. As such, many players learn by ear, by copying bass lines from records and CDs, and by playing in a number of bands. Even in non-mainstream styles, though, students may be able to take lessons from experts in these or other styles, adapting learned techniques to their own style. As well, there are a range of books, playing methods, and, since the 1990s, instructional DVDs (e.g., how to play metal bass). In the 2010s, many instructional videos are available online on video-sharing websites such as YouTube.
Sheet music from the 1920s provides evidence that the drummer's sets were starting to evolve in size and sound to support the various acts mentioned above. However, the first "talkies" or films with audio, were released circa 1927 and by 1930 most films were released with a soundtrack and the silent film era was over. The downside of the technological breakthrough was that thousands of drummers who served as sound effect specialists were put out of work overnight. A similar panic was felt by drummers in the 1980s, when electronic drum machines were first released.
Most basses have a volume potentiometer ("pot" or "knob"), which can be turned up or down, and a tone potentiometer, which rolls off the high frequencies when it is turned to the player's right. Some basses may also have a pickup selector control or switch, to select single-coil or humbucking pickups. Since the 1980s, basses are often available with battery-powered "active" electronics that boost the signal with a preamplifier and provide equalization controls to boost or cut bass and treble frequencies, or both. Some expensive basses have even more equalization options, such as bass, middle and treble.
Other kits will normally have 12" and 13" hanging toms plus either a 14" hanging tom on a stand, a 14" floor tom, or a 16" floor tom. For depths, see Tom-tom drum#Modern tom-toms. In the 2010s, it is very popular to have 10" and 12" hanging toms, with a 16" floor tom. This configuration is often called a hybrid setup. The bass drum is most commonly 22" in diameter, but rock kits may use 24", fusion 20", jazz 18", and in larger bands up to 26". A second crash cymbal is common, typically an inch or two larger or smaller than the 16", with the larger of the two to the right for a right-handed drummer, but a big band may use crashes up to 20" and ride up to 24" or, very rarely, 26". A rock kit may also substitute a larger ride cymbal or larger hi-hats, typically 22" for the ride and 15" for the hats.
Maybe you're looking for something a bit more conspicuous, that you can make into the centerpiece of your music room? If so, you'll want to investigate options like the Yamaha Arius YDP-142 and Suzuki Micro Grand Digital Piano. These advanced instruments sound every bit as gorgeous as they look, and they offer the ability to record your and store your performances to listen again later or even to playback as accompaniments.
