I was talking to Mark Zimmerman and we'll be getting together to add a tone hoop and upgrade this very nice banjo. Mark told me that all the banjos were of the same quality materials but the less expensive models didn't have a tone ring, neck binding and nicer inlay. After 35 years, I finally found one! :)
The Great Lakes Banjo Company was in business from 1974-1979 with a few completed after that date. They built a great instrument that has stood the test of time ..
...and are played by some great players, like Jim Willard Spencer!
