thumb|250 px|an acoustic bass guitar. the acoustic bass guitar (also called abg or acoustic bass) is a bass instrument with a hollow wooden body similar to, though usually somewhat larger than a steel-string acoustic guitar. like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned e-a-d-g, an octave below the lowest four strings of the 6-string guitar, which is the same tuning pitch as an electric bass guitar. because it can sometimes be difficult to hear an acoustic bass guitar without an amplifier, even in settings with other acoustic instruments, most acoustic basses have pickups, either magnetic or piezoelectric or both, so that they can be amplified with a bass amp. traditional music of mexico features several varieties of acoustic bass guitars, such as the guitarrÃ³n, a very large, deep-bodied mexican 6-string acoustic bass guitar played in mariachi bands, the leÃ³n, plucked with a pick, and the bajo sexto, with six pairs of strings. ==history==  the first modern acoustic bass guitar was developed in the mid-1950s by kay of chicago but the design did not show up again in a production instrument until the early 1960s when ernie ball of san luis obispo, california, began producing a model. ball's aim was to provide bass guitarists with a more acoustic-sounding instrument that would match better with the sound of acoustic guitars. ball stated that "...if there were electric bass guitars to go with electric guitars then you ought to have acoustic basses to go with acoustic guitars." ball notes that "...the closest thing to an acoustic bass was the mexican guitarron...in mariachi bands, so i bought one down in tijuana and tinkered with it."history of ernie ball strings and music man guitars - ernie ball ball collaborated with george fullerton, a former employee at fender, to develop the earthwood acoustic bass guitar, which was introduced in 1972. production of this instrument ceased in 1974, resuming a few years later under the direction of ernie ball's employee dan norton, who still works for ernie ball inc., until production finally ended again in 1985. the earthwood acoustic bass guitar was quite large (and deep) in contrast to most instruments in current production, which gave it more volume
