I purchased it to replace an original Floyd from the 80s. It is a direct swap of the original floyd rose which was and is made by Schaller. Everything is perfect,the quality,the finish, the parts,the packaging. And the arm stays put!No more wiggles.
It's EXACTLY the same as an original floyd rose it just has the "schaller" branded at the top. Dimensions, weight etc are the same. he quality though is better. It's a more solid unit than an original floyd rose. Can't find a con sorry. I was impressed that it was lightly oiled under the saddles. Talking about german engineering. HIGHLY recommended. If your guitar has a LICENSED floyd rose you need to replace the studs too .
