I've fiddled around with a couple of the Epis, but not really played them (I'm a lefty; they're not). They seemed fine for the money-certainly not a German Hofner- and I did like the controls a lot. I'm sure the controls on Hofners and other violin basses make sense to someone
; not to me, though. As for neck heavy; opinions differ, and I won't go there.
And no, they're not exactly what you'd call a versatile instrument, but if a violin bass is what you want, by all means, please yourself. I have 2 of them; an old Korean Rogue, and a Starfire. Both work just fine for what I like to play.
