I've heard a lot about fret wear but I've never really encountered it. I bought a 9 year old bass that plays beautifully but I'd like to know how to check for the signs. The tops of the frets aren't perfectly rounded anymore and they are a little shiny. The sustain is fine and I can't seem to find any obvious dead spots. What are the symptoms of fret wear? EDIT: Did a Google search and found what I needed. Thanks.
