Thanks for responding with an awesome addition to the list, Mslavik! Yeah, the bass became popular in the 1950s, thanks again to Leo Fender. But the very first electric bass dates back to the 1930s, when it failed to achieve market success. Interesting, huh?
And thanks so much for the kind words Susanmcgee, Pete46, and Limey1. Glad you guys got something out of the piece.
