I have a bass with newer Blue Steel strings that are very bright and I like that. But what I don't like is on certain upper frets I get a buzz from the back of the string. If I strike the string like a hameron but not a true hameron, just placing my finger on the frets as I am playing I can hear a buzz from my finger back to the tuners. Very annoying. The neck does not buzz any where on the playing pick up side.
