Here's mine. Acquired from here are few years ago, and fettled by Martin. It's early - serial number is "9". And the seller passed on to me an old Guitarist magazine which had a review of this very bass. It has the Schack circuit with dip-switches for EQ frequency. The two little black dots near the bridge are 3-position coil-tap switches. Oh, and it has LEDs in the neck-edge fret markers 😎
There is lots to love about this bass. It plays beautifully, and produces a huge range of sounds. As others have said, the necks are like nothing else. Two minor gripes: 1) The bridge has narrow slots for the strings to pass through. I bought a set of DRs to put here (the strings it has are awful) and the overwinding at the base means they don't fit. So now I don't know whose strings to buy! Any ideas? 2) It doesn't hold its tuning as well as my other instruments. This one I can forgive, though. All my other instruments are bigger, heavier, tankier things.
