Any body now if there is a difference between electric and acoustic string(steel string guitar), cause i've got a set older strings and on the "46" it says nickel wound electric guitar string and on the "13" it says electric or acoustic.
well most acoustic sets are Bronze 80/20 or phosphor bronze except for the unwound strings which would say electric or acoustic amd most electric sets are nickel or stainless so i would say you have set of electric strings thats missing the 10 or the high E
