Let me say first that I do not play any instrument. A few years ago my wife and I went to the Ridgefield Playhouse in CT. to see Poco. Rusty Young (who has passed) was still with Poco. On the stage there were several guitars. Seemingly they all were out of tune. Rusty Young was becoming frustrated until he came upon the last one which was in tune. He said, "Of course it's a Martin"
