The first guitarist in the Oscar Peterson Trio tgat I heard was Barney Kessel. When Barney left, he was replaced by Herb Ellis, who is probably the best known of Oscar's guitar players. For many years Oscar, Herb and Ray Brown comprised the trio and made many records together. When Herb left, he was replaced by drummer Ed Thigpen. Oscar also played with other guitarists, fellow Canadian Lorne Lofsky for one.
Near the end of his life, Oscar reunited with Herb Ellis and Ray Brown and I was fortunate enough to see them shortly before the end of his life. Oscar, Herb and Ray, my favourite incarnation of the Oscar Peterson Trio, have all left us now.

On my first two recordings of Joe Pass, Sounds Of Synanon and a Gerald Wilson Big Band album, Joe played a Fender solid body guitar, but still sounded like Joe Pass. In those days he was playing mostly single line solos and fewer chord melody breaks. He later switched to an ES175 and later hand made arch tops. Joe was a great guitarist, one of my favourites, but I would never call him, nor anyone else, the greatest guitarist.
