I had to cut and sand the feet to match the body of my violin (standard stuff), but after installing it, I realised that the strings were WAY too close together. I read a previous review of a person hitting multiple strings at once. This will do it. So I shaved it, sanded it and re-grooved it. It’s amazing that some of the strings had to be grooved almost 3mm over from what I received! It works, but it’s not plug and play like it claims. The one good thing, however, is that the sound is louder than my previous bridge. The tone is nice.
