If you’re looking for the best electric guitar strings for blues guitar, there are a few pieces of conventional wisdom that you should keep in mind. Traditionally, blues guitarists have favored heavier gauge strings because of their superior tone and tuning. While lighter gauge strings are easier on the fingers and facilitate string bending and quick playing, they generally do not hold up to the abuse that blues guitarists inflict on their instruments. So, if you’re into the blues, it’s probably best to pick a set with at least a .010 high E string, if not higher.
I would also recommend Ernie Ball’s new coated strings, which maintains the tone and tuning of their traditional strings and combines it with excellent durability and staying power.
