From a pianist perspective, when I was in college I played at a restaurant with an old beat up grand piano. I’d constantly complain about how bad it made me sound. Then one day I went to hear one of my mentors play on said piano. He sounded great. It was a pretty vivid demonstration of this principle for me.

One thing though, is that this title doesn’t paint the idea of amateurs with a great tone. Nothing wrong with being an amateur since it really means to do something for the love of it. I think pros need to be careful not to lose their amateur mentality wrt to the love.
