 In some country, rockabilly, or jazz bands, the bass tech might also be responsible for setting up, tuning, and maintaining an upright bass or electric upright bass.In some folk or acoustic bands, the bass technician may also be responsible for maintaining an acoustic bass guitar, which is a larger, bass version of a standard acoustic guitar.More rarely, some bass techs might have to set up a bass synth (e.g., as used by the bassists in some alternative bands) or bass pedal keyboard such as a Moog Taurus pedal, as used by Sting or Led Zeppelin.
