Yes, I bet that guitar has had it's electronics removed. Hopefully they are still with the instrument. They can be repaired. A friend of mine completely overhauled my Hyak's electronics. He said the electronics are no biggie, but some of the components are tough to get. He replaced them with similar valued components. If someone here snags this guitar, my buddy can make the electronics.
I am still on the lookout for a medium scale Hyak bass with this body style. It probably don't exist.
