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.
Eight and twelve-string models are both built on the same "course string" concept found on twelve-string guitars, where sets of strings are spaced together in groups of two or three that are primarily played simultaneously. These instruments typically have one of the strings in each course tuned an octave above the 'standard' string, although a fifth above is also used. Instruments with ten and fifteen strings, grouped in five courses, also exist, as do "extended-range basses" or ERBs with non-coursed string counts rivaling those of coursed-string basses.
In 1918 Baby Dodds (Warren "Baby" Dodds, circa 1898–1959), playing on riverboats with Louis Armstrong on the Mississippi, was modifying the military marching set-up and experimenting with playing the drum rims instead of woodblocks, hitting cymbals with sticks (1919), which was not yet common, and adding a side cymbal above the bass drum, what became known as the ride cymbal. Drum maker William Ludwig developed the "sock" or early low-mounted high-hat after observing Dodd's drumming. Ludwig noticed that Dodd tapped his left foot all the time. Dodds had Ludwig raise the newly produced low hats 9 inches higher to make it easier to play, thus creating the modern hi-hat cymbal. Dodds was one of the first drummers to also play the broken-triplet beat that became the standard pulse and roll of modern ride cymbal playing. Dodds also popularized the use of Chinese cymbals.
