While warming up for tonights service, I noticed the the "B" string on my RBV was buzzing faintly. I insulated the string at the bridge and nut....still there. Is it possible that the wrap is loose? It's no big deal, because I use the B string sparingly; thumpity- thump- thump. And I don't think anyone will hear it live or recorded. I have had them on for 3 months now, they feel very smooth for an ss round...warm too! Anyone else experience this?
