Nope , guitars, Any rosewood fret board can have a dead spot. It happens. Not common, but happens. thus the need to make sure. I had a guitar maker explain to me that is has to do with grains and glue.

My 40th annivesary Strat is rosewood fret board, not maple, midnight wine. My 72 Les Paul is fine. I don't have my Amercan Strat with a maple neck anymore. I can only play one axe at a time anyways. LOL
