You’re looking at Rudy Sarzo’s Peavey prototype for the Rudy Sarzo Signature Model bass. This is one of the very first prototypes made for Rudy in the 1980’s and its also one of Rudy’s favorites. It was used on tour with Whitesnake and it comes with the original case with a Whitesnake Japan Tour laminate attached to the case. The bass is also signed by Rudy on the body and the back of the body is taped over. There is no serial number on the bass as it is a prototype. A beautiful and brilliant playing and sounding bass. As you know Rudy is one of the all time great bassists and has played with some of the greatest musicians of all time. A must to own for any bass entusiast or heavy metal fan.
