Several colleges offer electric bass training in the US. The Bass Institute of Technology (BIT) in Los Angeles was founded in 1978, as part of the Musician's Institute. Chuck Rainey (electric bassist for Aretha Franklin and Marvin Gaye) was BIT's first director. BIT was one of the earliest professional training program for electric bassists. The program teaches a range of modern styles, including funk, rock, jazz, Latin, and R&B.
A well-known bass humbucker is the pickup used on the Music Man series of basses; it has two coils, each with four large polepieces. This style is known as the "MM" pickup for this reason, and many aftermarket pickup manufacturers (companies that make and sell pickups that you can custom-add to your bass) and custom bass builders incorporate these pickups in their designs. The most common configurations are a single pickup at the bridge, two pickups similar in placement to a Jazz Bass, or an MM pickup at the bridge with a single-coil pickup (often a "J") at the neck. These pickups can often be "tapped", meaning one of the two coils can be essentially turned off, giving a sound similar to a single-coil pickup.
The bass drum (also known as the "kick drum") provides a regular but often-varied foundation to the rhythm. The bass drum is the lowest pitched drum and usually provides the basic beat or timing element with basic pulse patterns. Some drummers may use two or more bass drums or use a double bass drum pedal with a single bass drum. Double bass drumming is an important technique in many heavy metal genres. Using a double bass drum pedal enables a drummer to play a double bass drum style with only one bass drum, saving space in recording/performance areas and reducing time and effort during set-up, taking down, and transportation.
