Fast forward almost 50 years, when Gibson plectrum banjos were in low demand, and it was transformed to a bluegrass 5-string with the popular Hearts \u0026amp; Flowers inlay pattern on the newly crafted curly maple neck made by Bob Palmer. The original shell was recut for a bronze Sullivan “Tennesee 20” flathead tone ring . The holes in the heavy maple shell, for springs that had supported the original archtop tone ring, were neatly doweled, and the grooved tension hoop was replaced with a heavier notched version. \r\u003cbr\u003e\r\u003cbr\u003eThis conversion was done by Bob Palmer, a well-regarded banjo wizard who also upgraded the plain maple resonator by making a lathe-turned top-tension style with curly maple that matched the neck. The result is a bluegrass banjo powerhouse that can hold its own in any jam session.","brand":"Gibson","offers":[{"title":"Default Title","offer_id":43078803652807,"sku":"GIBPB3-814223","price":3500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0503\/4947\/3991\/files\/1410251.jpg?v=1782290704","url":"https:\/\/www.gryphonstrings.com\/products\/circa-1925-gibson-pb-3-mastertone-conversion-5-string-banjo-used-13048","provider":"Gryphon Strings","version":"1.0","type":"link"}
