An acoustic-electric guitar is a hybrid; it's a hollow-bodied instrument with pickups installed to amplify the vibrations of the guitar top and body. Acoustic-electrics start around $80-$250 for beginning models, run $250-$900 for better quality and can run $1,000-$5,000 or more. A twelve-string acoustic guitar has pairs of strings that are strung close together and played as a single string.
For other uses, see Electric guitar (disambiguation). An electric guitar is a fretted string instrument that uses a pickup to convert the vibration of its stringsâwhich are typically made of steel, and which occurs when a guitarist strums, plucks or fingerpicks the stringsâinto electrical signals.
