After reading all the good reviews about Tributes I was a quite disappointed at this. Before even plugging it in I decided to return the guitar. Then I plugged it in and played it. Wow! Love the neck and action out of the box, intonation was dead on. Other than some burrs on the tuner side of the nut and the mice (

I am comfortable opening the control plate to get out whatever might be in there, but is this material inside (and being like a glue shaving) something to be concerned about? Sign of a hidden problem?
Thanks,
Hank
