1978 Gibson Quality / Prestige / Innovation catalog, page 12. Details of the Gibson EDS-1275 guitar. Double necked solid body with a twelve and six string neck.
The US list price for the EDS-1275 was at $1429 in May 1978. It sold very well in the late 1970s - 288 instruments shipped in '78 - a very large number by double neck standards. This catalog lists three finish options for this guitar: Sunburst, Walnut and White - unfortunately shipping figures for this model are not split by finish. By the time of the next (1980) catalog, only Walnut was listed.
