"The smoker you drink, the player you get" as Joe Walsh once put it. Unless the guitar is really badly set up, it is down to how it is played as to how good it sounds. If you have a good guitar, it will usually sound and play better than a laminated top Korean guitar. But get past this point and you have to work on tone production in the way you use your right hand. If you don't work on it, you will not get a better sound. This is even more true with high-quality classical guitars - if you don't work on it, a lot of them, eg. Fleta, sound awful. Incidentally, I have a very good Bacon & Day Senorita,which sounds excellent in the right hands - when I play it sounds sh*t! I get a better sound from my $300 Seagull.
