Was wondering if you guys might have an idea of some guitar method books Jerry could have worked through in the 70's...?
The "Howard Roberts Guitar Book" published in 1971 is probably one of them since Jerry says that he uses HR's "scalpel technique".
Guitar Player interview in Oct 78:
GP: "What kind of things do you do during these [learning] stages?"
JG: "First I go out and buy all the new guitar method books that have come out since the last time and read through them and try out ideas and exercises. The state of guitar education today is incredible compared to just 15 years ago. You can learn an astounding amount from just reading books that available today."
