Description: Gibson Super Jumbo 100 (SJ-100 or J-100) flat top guitar
Available: 1939 to 1943.
Collectibility Rating: A.

General Comments: This model was a less expensive version of the Gibson J-200. The Gibson J100 was half the price of the fancier Gibson J-200. Also the Gibson J-100's mahogany body is less brittle sounding then the J-200's maple body. A great model, please contact me if you have one for sale.
