Interesting, because there aren't many of these... this one is fashioned a lot like Jimmy J's original Custom '76 five-string, has the fan headstock and more of an earlier version of the Omega-cut body. I assume these are Signature 'tronics, and long-scale. Cool bass. 8)

I love that the ad lists it as 'masterbilt' . . . . . bub, if you only knew.
Yes, that's quite a glamorous presentation. I hope somebody buys it before it falls in the pool. :o
