Not to mention that the electric bass guitar was more affordable, much more easily portable, and required less storage room than an upright bass.
And thank god for that . Lugging an upright around can be a misery . And you lose that natural sound once you’re up to snare drum levels .Sound like a big Pbass .
I once loaded an upright into a friend's VW Beetle and rode home - the neck was sticking out the passenger door window, but I made it fit.
