Here are some pictures of my 2001 Mark IV short head. I also included a group shot with my Mark I and Studio Caliber. I am extremely happy with the Mark IV. Having never played one before, I think it sounds very similar to my Studio Caliber. I am running EL34's in the outside sockets and prefer them over the 6L6's. I am very happy with the Mark IV, although I still think the Studio Caliber is my favorite.
