Late George Harrisons favorite guitar was Gretsch 6120, i got biiig G-book where it says so, and i dont think it is about commercial angle. He was using it a lot. My fav tune is that "While my guitar gently weeps."
Was that Beatles or Harrisons own tune? i cant remember but it is a nice one.
There is something about that guitar that just gives me them goose-bumbs, sort of, its mother of all guitars.
