While I do think that there are perfectly legitimate settings, where electric bass and jazz mix perfectly well, and not just as a stopgap solution for someone who doesn’t have a double bass..
BUT
If we are talking about traditional straight ahead, swinging walking bass, it’s just not gonna get it done.
and that’s not to say that you can’t walk on electric, etc. etc, but if you are in a bebop quartet, that is not intentionally attempting a “modern take,” then it’s always going to fall short.
I think there’s a little more wiggle room in a big band specifically, as the intimate texture of a small combo has different demands than something so large scale. But I think that perhaps an even bigger reason is that double bass in big band was always kind of flawed, and thoughtful electric tone simply does a little bit better of a job without ruining the whole vibe.. contributing to that would also be the fact that even fairly traditional-minded big bands simply sound significantly more modern, almost inescapably.. due to gear/technology, and just the almost exclusively novelty/academic/period-piece nature of big bands that are playing older, music, and styles.. whereas there still exists some thing of a cutting edge of jazz combos, which can reasonably be experienced in something resembling the original setting and intent..
And this gets talked about all the time, but of course, there is a whole rabbit hole of trying to simulate a double bass on electric.. keeping with the same theme of a combo playing in an old style, I still don’t think even a very well done pseudo-standup setup really gets it done, but I think the cut off line of exactly what settings and style “work” with electric becomes a lot more generous and open if you’ve done a really great job of making your instrument and play style sit in a usable place.
Gustav Broman, look him up, just a fantastic job of not only making his electric bass go “thunk,” but in making his play style and vocabulary reflect some of the grammar and idiosyncrasies of good double bass jazz playing. Which is the other part of it… If you’re trying to play old music and you’ve just got to use electric bass, it takes a lot more artistic intention and effort and attention than simply ‘using flats and a foam mute’
here’s a random vid I found of Gustav Broman’s trio
I think an interesting thing to consider, when analyzing the success of a double base proxy is whether WHEN THEY PLAY FAST AND NIMBLE STUFF / SOLOs,
does it sound like a good upright player, and not just an electric taking a rip.
