Ernie Ball 3120 Coated Slinky Struny pro elektrickou kytaru

They definitely stay crisp longer than regular Ernie Ball strings. To my ears the wounded strings sound a bit brighter than the regular ones as well. If you like regular Ernie Ball slinkies, but would like that the strings stayed fresh longer, give these a try. The set that I put a month ago still sounds as crisp as new.
