Ever since I bought the YDS-120, I've been interested in it and made various things myself. I finally made something I'm happy with. It solves the problem of accidentally getting sheet music wet or noticing it's wet when you look down. I use it by folding a tissue and putting it inside. Spit stopper, 2nd generation, improved from the first model, increasing the contact area. This has achieved improved fixing power. Fits the loose, square cone of the YDS-120. Thank you for viewing.
