I have just gotten Anthem installed in my new Collings D2HA. I love the natual sound in general. But I found that only one note (the 2nd string the fourth fret from the nut) makes "too much" metal sound in mic mode. When changing to undersaddle pick up mode, it comes back to "regular" sound. I wonder why only that particular note makes that too much metal sound. Any one knows? Thank you.
