However, now that I have a series to review (thanks!) in reviewing it further, it is a S900, not S600. It is a Neck-through Design, not bolt on neck. It has only 1ea Volume, Tone as pictured (not as described). It has the Mini-toggle Killswitch for Each Pickup and no 5-way selector switch. with a Steinberger KB.
But thanks for getting me in the right direction!
