Lefty, of course. Stacked vol/tone knobs, passive, P/J Nordstrands, ebony f/b with dust pore-filled into body, which is mahogany, maple/carbon fiber neck, asymetrical body for added strength. Cavity pre-routed for additional pre-, pup covers for changing pup styles. This was the first bolt-on that he had produced, which is what I wanted. Great fit.
Skip is found here at TB, usually in the strings (Circle K), but he has an ancient, non-updated website at Knuckle Guitar Works.
EDIT: I perform twice monthly at two old theaters on the "Historical Sight" registry, and both soundmen love this bass. They actually run it flat with the lows rolled off just a touch. It records quite well.
