Twenty-year GAL member Jack E. Johnston got into guitar making when he needed a lighter instrument than his 16 lb. banjo. A good guitar was too expensive, so he built one. He has studied with Charles Fox and Alan Carruth, has degrees in mechanical engineering and photography, worked at Lawrence Livermore National Laboratory for thirty years, and plays in The Bluegrass Gospel Boys Band.
