So I was in a GC on my lunch break Friday and there were two cherry Epiphone Dot's. One appeared to be a 2013 and the other 2014. The 2013 appeared to have a maple center block, and sounded brighter, and much more open. The 2014 appeared to have a mahogany block, was much darker acoustically (more than just the center block could account for), and sounded deeper and more mellow. The 2014 felt a good couple pounds heavier as well. Anyone know more about what changes have been done over the years? Or is it just that there is a lot of variation between the different examples of the model?
