I think a good combo for a loud, punchy dread with some cut to is would be an Adirondack topped Honduran Rosewood guitar. The price of the Honduran and availability of it makes it a great alternative to Brazilian as far as sound goes. I have built a Brazilian and a Honduran Rosewood dread, and was able to compare them side by side. The Brazilian one went to a hard playing bluegrasser, and the Honduran to a good friend of his. When they came to pick up the Honduran, the BRW owner brought his guitar with him. Keeping in mind that the BRW had about 5 months of hard, daily playing put into it, I got to hear the same guy play both guitars. My impression was that I would not have given you a nickel for the difference (the BRW may have had a slightly mellower tone, but it also had some months of playing put into it). Both were giving a banjo a run for it's money. I also got to watch the psychoacoustic principle at work when a friendly argument broke out between the two guys over which one sounded better.
These 2 guitars were built as close to identical as I could get them, at least by my standards, because the Honduran owner wanted it that way.
This is not to knock good ol' East Indian Rosewood though, because it makes for some good dreads too!
