A quick Wiki-search will back up Bernard's assertion, somewhat. Gibson rejected 'the log' solid body design, came up with their own and asked him to endorse it. After suggesting come cosmetic, component and materials changes he signed off and the rest is history.

Btw, I agree that his post-Beatles material is sorely lacking. It would seem he needed John's BS-meter to keep him on his toes. And when one watches old footage(God bless youtube)it's obvious he was light-years ahead of everybody, musically. John said one of the reasons they broke up was because he and George got tired of being Paul's back-up band. But, that's a whole other discussion.
