I agree with the OP. Just as a parallel comparison because it shows up in other activities as well. I used to sail competetively. I was not bad, I took 5th place in the national championships in the C-15 class. There was a guy out of California that was in the top 3 of our entire fleet. He came to Dallas once for a regatta, but didn't bring a boat. He borrowed a boat from a guy who had just bought it but wasn't confident enough to compete in a regional event. The boat was plain stock. He kicked butt. My boat was excessively tricked out, but all I got to see was a lot of his transom. Sort of like taking a brand new Fender P out of the shipping box, tuning it, and playing a major venue.
So, yes it is the player. The instrument would have to be falling apart before the player would sound bad.
