I have a floyd rose on my guitar, and for the life of me I can't get my high e string to stick in the part on the bridge side. Basically I have to use my whammy so I can unscrew the one part, and I stick my high e string in there, and tighten it again, but it never seems to actually latch on to the e string. I've tried this over and over and over but I can't get it to actually grab onto it. Help please?
