Hi, I recently went to the Martin Guitar Factory for a tour (you should do this if you haven't ever been there)... While there, I played a Martin D-18GE, which I thought had amazing sound qualities. I had never played or seen one before. Unfortunately, it's really expensive. I've been considering purchasing a D-28 for some time now, but I'm now wondering if a D-18 would be a better choice. I was just wondering what the difference is between the two models. Are the body styles somehow different? I can't really tell... I'm not trying to compare the GE with the base D-28, as I know some of the big differences there. Just wondering from a model perspective how different the 18 style is from the 28? Any thoughts/comments?
