Hi there,   I have always wanted a Variax, but because I am left handed I could never get the newer ones. I see the older Variax 500 was in lefty, but they are pretty rare and go for high prices. So I decided to buy a brand new one and do it myself. It's not that hard, I promise and I am no luthier. You will probably void your warranty so do this at your own risk!   1.  Remove all the strings.   2. Remove old nut by using a small block of square wood and gently tap
