Hello guys, I have a silly question. I need to change my strings, and I don't know the exact model of the strings that I'm using, but I like them, so I want to buy the same set. I am pretty sure that they are GHS. At the end they have black silk, at the ball end there is no silk. And the core on the E string is visible. Thank you! PS: The strings came without a package, thats why I don't know anything about them. Edit: And they are roundwound.
