Acoustic-Electric Guitar
Introduction A thin body acoustic guitar is a
hybrid instrument that combines the body shape
and size of a solid body electric guitar with a
flexible soundboard and a thin, hollow body. It
is designed to be played only when plugged into
an amplifier. The output can be tailored to have
tonal properties of either acoustic or electric
instruments, making it suitable for a number of
different musical styles. This instrument was
designed to be easy and inexpensive to produce
while still having good sound quality. It will
eventually be used as the basis of instrument
making workshops for high school students.
