Quality of the tremolo is pretty solid. But why the 1 star? I ordered nickel one and got a chrome one instead. Dissapointing, kinda ruining the look of my guitarbecause everyting is nickel on her, but I'm not much worried about it. And where are the claw and the springs? It is clearly listed as that they are included but only the tremolo came in the package with the tremolo arm and 2 posts (plus some allan keys). If I didn't have some spare parts it would be very dissapointing. I had some trouble mounting it on my evh standard, had to route the body a bit, but nothing much. The tremolo has to stay approx. 5-6 mm above the body of the guitar which makes it kinda ugly but it works. If not, it buzzes, which makes it have a higher action, which is okay for me, but maybe not for someone else. The shipping was very fast though.
