Kel Kroyden was a subsidiary brand of the Gibson Company. The model originally came with no tone ring, and also no adjustable truss rod. However, it is now after-market equipped with a modern 5-string neck with an adjustable rod, and a 1989-1990 Huber 20-hole flathead tone ring. Kel Kroyden banjos are said to have been produced only between 1930 and 1933 – during the Great Depression -- and they typically have no serial numbers. This WAS $6180 but it is NOW ON SALE.
