This is an updated review. I am happier with this now that I made a few simple changes. I straightened the L shaped brackets that keep the harp from falling out the back. This caused them to break at the 90 degree bend. I then bent them back up with my thumb. The bend starts as they exit from under the bar. I stopped about 15 degrees from straight up. Before I did that I swung them around 180 degrees on the rivets so they came out the other direction. That is because I also swung the neck brace around. The ends of the neck brace point down slightly. The harp was low for me. Swinging it around made them point up, raising the harp. Perhaps the standard way works better for others. This puts the thumbscrew on the left but that's OK. I also took a Dremel tool to the rivet heads that were scratching my harps and took them way down. I did that before bending the brackets and the rivets held just fine. I probably took 70% off the tops and smoothed the edges flush to the bar. This holder now works great for my Lee Oskar diatonics and Suzuki tremolo harps. I also replaced the hose on the neck part with a 3/8 ID X 1/2 OD clear vinyl hose a foot long. 35 cents at Lowes off the bulk roll. The original hose didn't cover the ends of the neck brace.
