It was with no hesitation I ordered the GX having had the EX for 7 years.
Thomann delivered with speed and I was impressed with the correspondence right from the beginning.
I saw no difference in the two models except that on the C key there was cork on the GX and a small post on the EX. Apart from that very similar.
BUT, there was a subtle tone difference, slightly mellower. I just can't wait to enjoy this GX for many years to come, you can not go wrong with Muramatsu, top class instruments, and Thomann delivered on price and speed.. THANK YOU!!
