Why do blues musicians use electric guitars?
Initially, guitars were amplified in order for them to be loud enough to be heard. Guitars in big bands were not able to compete with traditional instruments. At first guitars were mechanically amplified with companies like Dobro and National making guitars with a resonator inside. When Fender and Gibson invented and produced electric guitars, they could be heard and could take a lead in bands. Blues musicians used them for the same reasons. They could be heard above the noise of an audience in a concert hall, rent party or hootenanny.
