7 year old strings – What is the difference in sound?

I was asked to do a recording session where I needed to use my old ES-175 which I hadn’t changed strings on in more than 7 years.

I took the opportunity to make this video of how the difference is in sound through my setup. You’ll probably find it a bit surprising :)

The strings I use on this guitar are .12 D’addario Flatwound Chromes like these: http://www.daddario.com/DADProductDetail.Page?ActiveID=3769&productid=62&productname=ECG25_Chromes_Flat_Wound__Light__12_52
