[font=trebuchet ms]All three offer very good price/quality, but there are some differences from one price range to another.
Entry-level Yamaha guitars are excellent quality for the price. Low-level Ibanez are not as good. Godin doesn't have much to offer the beginner. As you move into intermediate price range, all three companies offer very good instruments. At the top end, Godin moves a bit ahead of the other two, but at that level, the differences are very subjective matters of opinion, and it's harder to say that one one guitar is really better than another. All of them are well-made - just that one may be better suited to your tastes than something else.[/font]
