The Gretsch bass is from 1963, I was told it was a ´supertron´but not sure. My gruhn´s guide say little about these basses. It is looks like a filtertron with blades.
It sounds really good, but the pickup lies on top of the body - cannot adjust it´s height. If I lower the action for better playability, the strings hit the blades. Maybe a neck reset is needed.
But the acoustic sound, wow....
