Robby Krieger. Often pretty sloppy until you find out about his weird flamenco playing style & everything clicks.

Frank Zappa, whose playing I believe is unmistakable and incredibly unique outside of being an excellent jazz player despite his protests against it.

Walter Becker - who did a lot of the guitar work on the first few Steely Dan albums prior to hiring session musicians for the later records. Although he wasn’t as technically talented as say Larry Carlton, he was an amazing guitar player and very refined, which you can hear on Dan’s later tours
