Somebody mentioned the Taylor GS. I was pretty much of the opinion that Taylors did not interest me at all (and this is after having owned a 110 dreadnaught), then a while back I was in a store and picked up a GS (if memory serves, it has been a while). I was really surprised. It did not sound like the typical Taylor. It had more depth and warmth to the sound. It was the first time I had heard a Taylor that sounded like that. I have not sought one out since, but would be open minded if one came my way.
I have to say that I think that Collings guitars are over-rated. Maybe not the most over-rated guitars in the world, but I don't think they live up to the hype and price tag. They are impeccably built, I will give them that, but their sound always leaves me cold. I have played quite a few of them, and always have the same impression. Not really sure what it is about them that I don't care for, but I don't envy those that own them.
