I bought this bridge as a replacement for the Kahler X Trem, that came on one very guitar that I bought in small store in Berlin. Pretty old, but gold. However the original bridge was a terrible piece of sh*t, so I?ve decided to give this one a try. Honestly... It works. It really does. There are a few things you have to tweak before you can use it, mostly balancing the string/spring force, that may be a bit tricky, cause you set it up with a hex wrench from the top of the trem. Other than that, It is rather easy to use and install.
It is not a bad trem, but still, goes out of tune sometimes, especially the top E string tends to go flat after some time. Also the bar is wiggling a bit, but nothing to worry about. The only problem about this bridge is, that you won?t find it on almost any guitar and it is very specific in terms of picking hand ergonomics. It is kinda hard to go from Kahler to Floyd and vice versa. Get used to one or another, because both are very different in terms of picking hand position, so it may feel a bit uncomfortable in the beginning.
Also keep in mind, that it is almost impossible to use this with any string gauge thicker than 58, you just won?t be able to attach the strings to the bridge due to the fact, that those string hooks are not exactly big and thicker strings just won?t fit. So using this in B standard with 13 - 60 gauge is almost impossible. Also springs in the back of the trem are not exactly strong and you may run out of tension, if you use anything thicker than 10 - 46 in E standard.
But if you want a locking trem and Floyd is not exactly your thing, I do strongly recommend this product. I think you won?t be disappointed.
