Thanks for the replies.....I actually have the 1997 issue of Guitar Player where it is stated that he used the Cry Baby and Ampeg Scrambler, but I'm a little sceptical because it sounds on studio recordings at least like he is using a fuzz, not just overdriven amp on some songs, but the Scrambler did not come out until 1969! So maybe he had that in use at Woodstock, but for recording Baxter's? I don't think so. Anyway, not a burning question, I'm a garage guitarist and like to try to replicate tones with the original equipment. Now I have to go track down the 4 live concert CD's recently released.
As an aside, I was a little late/young to see them live in the Airplane days, but have attended Starship concerts in 1974/75?-Spitfire tour in Miami, 78- Earth tour Cleveland and about 1994- Deep Space tour at Valley Forge.
