Thanks for the info! After some further research it does look like a Pirastro Gold. The winding at the top is green. It seems like there are multiple Gold labels Pirastro – http://www.violinstringreview.com/e-strings.html
Does it matter which ones are good? It seems like the Obligato E string whistles : http://www.violinstringreview.com/obligato-e.html
How do I know which brand it is, or are they all the same? I read Wondertone supposed to be better.
Or should I just try getting the Hill Medium strings? It sounds warmer on here : https://www.youtube.com/watch?v=SLz_QQFnsDc
