I used this tremolo to replace the floyd rose on one of my guitars. By the measures it was supposed to fit, but it didn't. My luthier managed to install it and it is very well built. The tremolo block is magnificent, brightened the instrument and brought much more sustain and overall tone richness. But then the problem was strings breaking. Tried a lot of solutions, but ended up changing saddles. After that everything works perfectly. Does not have to mean that the saddles were bad, when replaced the floyd rose the angle of the bridge and the neck was higher then average.
