Attention Gibson® fans! Here's an impressive full-scale 4-drawing set of specifications for a 1957 Gibson® J-45® acoustic flattop guitar, drawn by luthier Michael Collins. Details include a fret scale chart, complete bracing profiles and neck joint dimensions, plus materials specifications. Build your own guitar, or display these handsome drawings on your shop wall.
Measurements were taken directly from a 1957 model, but bonus drawings are included that reflect production variations during the '40s and '50s: large and small pickguard profiles, peghead logos, 3-ring and 7-ring soundhole purflings, neck laminations, and three different bridge styles.
