I'm calling it a JV SQ. Check out the neck on this. No plug, no skunk stripe. Take a look at the pencil marks on the neck and the way the truss rod against the rosewood board. Truly rare to see this and another sign it's a JV neck for sure. It also has an American pickup. Yes another JV sign. Plate says SQ but, zero as first numeral makes me think it was early. Serial number dates it to 83-84 made at the Fuji-gen Plant. Well known for quality manufacturing. Recent pro set up. Weight approx 8lbs. Will get nut measurement later. The bass will be properly packed and shipped with a gig bag. It ships from LA area and will need 48 to 72 hours from payment to shipping.
