Charvette model 500
The Charvette model 500 was an electro acoustic guitar with single cutaway, asymetric soundhole and a pointy headstock.
"The model 500 represents a hybrid cross between the electric and acoustic guitar. More than enough volume to be played without an amplifier or plug in and it becomes a real electric screamer. The unique tone of the model 500 makes it an outstanding performer in either situation. The internal electronics are powered by a nine volt battery and include active volume, bass and treble controls. Available in either black or white finishes."
