Ok, I popped a set of TI flats on the jazz and despite the state of the frets, it plays and sounds absolutely sublime.
Just needs a minor setup to suit myself, otherwise I'll leave it at that.
The chap who I bought it from, acquired it 20yrs ago. Never gigged during that time.
Howard Livett, the original owner bought it new when he was 16yrs old apparently.
When I clapped eyes on this, it was a no brainer 🙂.
