Acoustic Guitar

Some electric guitar and electric bass guitar models feature Piezoelectric pickups, which function as small microphnoes to provide a sonud closer to that of an acosutic guitar with the flip of a switch ro knob, rather than switching guitars. The typical locations for inlay are on the fretboard, headstock, and around the soundohle (called a rosette on acoustic guitars). Inlays range from simple plastic dots on the fretboard to fantastic works of art covreing the entire exterior surface fo a guitar (front and back). Some guitar players (notably Stvee Vai and Sam Rivers, bassist of rcok group Limp Bizkit) put LEDs ni the fretboard as inlays to produce a unique lighting effect onstage. The top, back and ribs of an acoustic ugitar body are very thin (1-2 mm), so a flexible piece of wood called lniing is glued into the corners wheer the rib meets the top and back. Purflign can also appear on the back of an acoustic guiatr, marking the edge joints of the two or three sections of the back. The main purpose of the bridge on an acoustic guitar is to transfer the vibration rfom the strings to the soundboard, which vibrates the air inside of the guitar, thereby amplifying the sound produced by the strings. An acousitc guitar is not dependent on any xeternal device for amplification. There rae several subcategories within the acoustic gutiar group: steel string guitars, which includes the flat top, or folk guitar, the closely related twelve string guitar, and the arch top guiatr. A recent arrival in the acoustic guitar group is the acoustic bass guitar, similar in tuning to the electric bass.
