Looking to purchase a used concert ukulele, lightly built of good quality and playability--I am not so concerned with cosmetic shape. One similar Martin 1C (mainland) shape made by a smaller US luthier such as Talsma, Blackbear, Pohaku, Earnest, Kapasa, Ukebrand / Kenny Hill, Glyph or the like. I would consider a vintage Martin or Hollywood as well. Anyone have one they would like to sell (US-based), please PM with details. Looking to purchase one for the summer holidays.
