Okay so i got a white guitar and i was wondering if dirt will show up easily from like dirty hands and such. Mainly on the neck .
Cause i spent alot on my guitar and i want it to look GOOD.
It will turn yellow over time. And there's nothing wrong with that, just like scratches and chips.
I have a black strat and in the light or in pictures smudges show up alot worse, more because a smudge seems a lighter color and with white it doesn't show up as much.

Do you mean will it fade and turn yellow? yea, most likely. def keep it in a case and away from sunlight. what shade of white is it?
