This. It's the fact that it has a larger ranger than a grand piano that stuns me. 14.2 hz. I think the only reason he didn't go lower is because any listeners would have bowel trouble. I also think it's neat that they had to invent a new bridge just to get that high string on there. This site has lots of stuff on it... I just wanted to focus on the bass... which is why I put it in the basses section.
