I'm assuming you mean covers like the ones on a Grabber or LP Triumph. There is at least one person selling brand new reproductions, and every so often a real one shows up. I got one that way. Even if they're making a bass now that comes with a cover you'd be hard pressed to get one - Gibson's not much for parting stuff out.
