I've played that bass and I know where it is. Been there for close to a year. I told the guys in the store where it's consigned that the serial number was off. The nut is weird as well, not brass and quite large, possbily ceramic. I've checked for signs of a different serial number but could not find any. The store is going back to being an internet only business so I can't go there and check it out some more, as they closed doors a few weeks ago.
I have to say that through the 1/4 inch jack there was quite a bit of noise; can't say how quiet or noisy it would be through the power supply, so a trip to Santa Rosa may be needed. Nice sound otherwise.
