Here's a nice video shoot-out between the standard D-28 and the new D-18 ... I'm biased, but I like the D-18. I bought the D-18 after personally making a similar live comparison.

"QUOTE" warfrat73 ... why would I spend the money on a D-18 Authentic if it sounds like a D-28? Doesn't buying a hog guitar that sounds like rosewood arguably defeat the purpose of buying a hog guitar?"
