I am playing mandolin professional and i need good strings that last for a while and will give a great and a bright tone. I have A style and F style mandolins and I used many types of strings like : Elixir, Martin, Thomastik, GHS and other. The Daddario EJ74 are my all time favorite. Great quality, crisp and balanced sound. Fits great to my style.
Please take care that there are 2 types of strings. The ones with loop end and those with ball ens (like electric guitar) so order what is fits your instruments.
I will keep use the Daddario EJ74 for my mandolins and highly recommend them!
