I saw a couple Offspring videos on MTVX last weekend and I noticed that their bassist, Greg K., has a pretty unusual looking bass. It sorta looks like a Jazz bass, but with a 2+2 headstock with the tuners arranged really weird and a rickenbacker style bridge pickup (but without the cover). I have no idea what this bass is! Someone shed some light please! By the way, the videos I saw were, "Original Prankster" and "The Kids Aren't Allright."
