My mahogany guitar came unpolished from the factory. After several years of play, certain areas are now quite shiny -- from self-polishing due to contact with my body during play. Especially the back of the neck, the area where my arm rests, and the part of the guitar the rests on my leg.
The shine doesn't look bad -- only strange because it is in select areas.
I am wondering first of all if it is bad for the guitar (will it cause degradation of the original materials?) and second of all could this effect the tone of the guitar?
Would it be better to remove the 'polish' somehow -- or find some means of polishing the rest of the guitar to create an even appearance?
I imagine this happens to all sorts of instruments.
