I'm just going to straight out say that the Epiphone Jack Casady Signature has more than transcended JC's use of it. I would go so far as to say it has become over a 27-ish year production run (and counting) one of the go-to answers to the question "which long scale, hollow bodied electric bass should I buy?"
I don't think I've ever played a lick of Jefferson Airplane or Hot Tuna on mine. It's a great sounding bass regardless of the genre being played.
Furthermore, I don't feel pigeonholed by any bass. I don't give a crap what other people think of the bass I'm playing. I pick them on a whim and if anyone has a complaint, they're welcome to come on stage and take over and do a better job. I'll play a Mockingbird or an Explorer in church, or at a country gig, and I'd play metal on my JC because I DGAF. People who complain about these sorts of things should remember that they use their ears for listening, not their eyes
