Does anyone have any thoughts on the differences in sound with the YAS EXS and the EX? I currently own the silver plated horn and love it; however I played the EX the other day and found it to be much more darker in sound; as one might expect. Also, my sliver horn has a G1 neck whereas the gold horn has a V1 neck. I am not familiar enough with them to know the differences in the necks. I am very much thinking about selling my EXS to get the EX. Any thoughts.
