I recently got into harp playing a few months ago, to learn a few folk songs(dylan, Young, Pety, etc) and use it to accompany my guitar playing. When I picked up my first harp, I picked up this holder to use with it. After using it for a little while, I found out that it does fit my neck good, and stays in place, but some of my harps, like my Hohner Special 20s and others do not fit to well or rest to well in the holder. They set to far back. My Lee Oskar harps fit better, because they are a little bit wider. Thats just my observation. Mine has the big black wingnut on it. I also bought the Hohner 10 hole holder, which I think fits me better, but its made in China, where as this one is made in Germany. Oh well trade one thing for another.
