I have an old Czech upright 3/4 size double bass with a Strad label made in Czechoslavakia. It is a roundback with violin corners. It has the fancy purfling below the button like a Juzek. Last year I had a new high quality ebony fingerboard and a new adjustable bridge installed. Fingerboard is a couple inches longer than normal. Bridge blank is a Aubert Luxe made in France. Strings are Spirocore. Bass has very good sustain. It has a cleated on each end top soundpost crack and an expertly repaired heel, I'm pricing it lower than I think it would normally sell for because of this. $7500 call Jim 504-559-2384 I'm 20 miles west of New Orleans.
