As always, the Fiddleshop guys are great but this product isn’t. I bought 3 of them and was disappointed in them all. They came apart while I was trying to put them on the fiddle. I super glued them so they would stay together which worked but once installed I found they rattle distorting the sound. I had an older one which had less arch and didn’t fall apart that worked much better but I don’t know if they can still be purchased. I ordered the Tourte mute and found it to be much better although far from perfect too. I would not recommend this product to anyone.
