Santana played a red Gibson SG Special with P-90 pickups at the Woodstock festival (1969). During 1970–1972, between the release of "Abraxas" (1970) and "Santana III" 1971, he used different Gibson Les Pauls and a black Gibson SG Special. In 1974, he played and endorsed the Gibson L6-S Custom. This can be heard on the album "Borboletta" (1974). From 1976 until 1982, his main guitar was a Yamaha SG 175B, and sometimes a white Gibson SG Custom with three open coil pick-ups. In 1982, he started to use a custom made PRS Custom 24 guitar. In 1988 PRS Guitars began making Santana signature model guitars, which Santana has played through its various iterations ever since (see below).
