Overwater 6 String Bass late 80s

Description

Condition is excellent with very little use, late 80's or 90's, I'm not sure. UK built.
Plays and sounds well, tone knobs are a bit scratchy and I never really got on with them, should be an easy fix or replacement for someone who knows what they are doing. Comes in original hard case with strap locks. I of the machine heads were replaced, all else seems original.
