Buying strings can be difficult with so many choices out there. I have used EB strings for MANY years and have never gotten a bad set. They are well made and seem to have a long life. These are no different.
As I said, I have always used them on guitars and basses, but whenever I am unsure what strings to buy for an instrument, EBs are my go to brand. Be it a mandolin, banjo or in this case a 12 string...
If your not sure... try a set of Ernie Ball strings, they are always a safe bet!
