Wylie Gelber comes from one of those build-it-yourself families, so it only makes sense that he and his father constructed a pair of 4-strings that he uses on the road and in the studio. His No. 1 is this Model III which features a 1960s Gibson mini humbucker in the bridge and a ’70s-era Gibson Ripper pickup in the neck. The body was carved out of two pieces of 40-year-old alder. The neck is from a ’70s Gibson Grabber with a reshaped headstock. Gelber keeps it strung up with D'Aquisto flatwound strings (.050-.105).
