If I understand my history correctly, The first electric bass was made by Leo Fender for use by upright bass players. bands often included an upright acoustic bass. They found that in larger venues, they often could not be heard above the electric guitar amps. Upright bass players would record on the upright and then use the electric for live shows. obviously They played the same notes and used the same techniques. So: If its decended from an upright bass cello, how come they call it a bass guitar??
