I have decided that the distinction between acoustic bass and electric bass (and guitar, but we'll leave that aside) is meaningless. When I go to hear a band, everything is amplified, almost always. I went to hear a jazz group: the flute was amplified, as was the bass, and the singer. When I listen to jazz, there's this huge emphasis on which instruments belong, and which don't. When I listen to (or read the comments of) upright players, they sound obsessed with making the amplified upright sound like some imagined version of an acoustic upright. It seems that some styles -- in particular "mainstream" jazz -- on what instruments belong and what instruments don't, usually on some basis of "acoustic" rather than electric. I think it's nonsense. A Hammond organ is a synthesizer. A muted trumpet played through microphone, drenched in reverb, is an electronic instrument. If all the acoustic instruments end up being amplified in the end, altered by electronics, as they do, then the distinction is a false one.
