Did you read the link I posted from Fender's site? Rev J is correct.
I didn't say he was wrong, I said he was only partially correct.
His comment seemed to imply that the electric bass was invented for guitarists not bassists. Yes the article mentions the addition of frets which is why it was called a Precision, and that guitarists could more easily pick it up. But his point was that Leo didn't intend for it to be a replacement of the upright. Yet the article specifically calls it the successor of the upright:
"Its predecessor was the age-old upright bass," It also mentions portability, "a large, bulky instrument that took up a lot of space in the touring bus," and the volume issues, "and had become increasingly difficult to hear as bands grew louder." and...
"Given the brash horn sections that provided the main voice of many dance bands, the inherent loudness of drum kits and the advent of better electrified guitars with better amplification, something needed to be done for bass.
And by 1949, bands certainly were getting louder and smaller."
The article also lists a number of prominent bassists at the time that Fender got to market for them. No where in the article (or anywhere else) does it say that it wasn't meant to replace the upright, which is why I said his comment wasn't entirely true.
