Up for sale is my Traben Chaos Core 4 string bass, Black Vapor with maple neck in excellent condition. There are 2 Rockfield Musicman-style pickups, with a 5 way selector switch. The original Aguilar OBP-3 preamp is installed. This is the made in Korea version before B.C. Rich bought the company. The bass comes with a gig bag. I don't see any wear marks on the bass at all. The only issue with it is that it has a scratchy volume knob. Asking $325 shipped CONUS.
