I've been into short scales for almost twenty years, and my gigging basses are JMJ mustangs.
Anyone who dismisses short scale basses is in danger of sounding like an ignorant tw@t — like Scott Devine does in the SBL video, even if it was tongue in cheek.
If anyone says their reason for not considering a short scale is that they'd look ridiculous playing it, they need to remember that many punters can't even tell a bass from a guitar, a short scale bass is bigger than a guitar, and there are plenty of people who can play guitar in public without feeling self-conscious about it.
