Example of How a Guitar Finish Can Darken Over time – 2002 Epiphone Les Paul

I was changing out my strings today and noticed how the finish under the bridge was lighter than the rest of the guitar. I thought I would try to show how the the finish on my 2002 Epiphone Les Paul has darkened. I hand this guitar on the wall most of the time so I assume this has contributed to the shade difference on the expose top.
