I've never seen one of these before. http://cgi.ebay.com/6-String-Steinberger-Could-Be-One-of-a-Kind_W0QQitemZ7383359159QQcategoryZ4713QQrdZ1QQcmdZViewItem Something looks a little odd to me. Zero feedback never inspires much confidence -- probably a scam. THe no serial number thing is a real alarm bell. If I were actually interested in this bass, I could in theory ask the guy if I could see it since I live in Portland, but sixers aren't my thing, and this model definitely isn't all-graphite, so it's not for me.
