Fenders invention of the precision electric bass guitar revolutionized the music industry. Having an amplified bass guitar allowed the bass guitar to be a prominent part of any band. An electric bass guitar was also much easier to pack and carry. The electric bass guitar is a major instrument in most bands today thanks to Leo Fender.
