Did Cliff Burton have a blonde Rickenbacker as well as the obvious red one? That's the question here. In the top picture I first thought it might have been the light. However, in the 2nd picture you can the same bass behind Kirk. Clearly without Eb0 neck pickup, which was added during the recording of Kill 'em all. At which point Cliff and Kirk hadn't shared a stage together. What are your thoughts? Is it an unknown spare? Or simply the red one under strange light conditions?
