Just joined the club with a new Mercalli 4 in Alpine. Stringed it up with a set of TI flats.
Wow!
Wrt to thru body setups, I did string mine thru body. Now I'm not sure what the differences would be otherwise, I haven't tried it top saddled. But I will say that the body resonates in a way I've never experienced before and I've never played a thru body before. I can feel each note through the body. Maybe it's the thru body setup, maybe the korina body, maybe the high mass bridge, maybe the sum of it all. Who knows.
