This tuner is from the right side, the direccion of the turn is the same than 3 and 4 strings
Actually no its not as the string is wrapped the other way around the posts...so you will have to turn it backwards
Sounds like blush which is trapped moisture. Can be caused by humidity. Sometimes It can go away on its own if you leave it in a dry room for a couple of days. Or you can use blush remover (flow out) which basically softens the last few layers of nitro and lets the moisture escape. Pretty sure you can buy that stuff anywhere but I know for a fact that Reranch sells it
