I am using Fender Tele American Special and Fender Blues Junior tube amp with nearly ten effect pedals. I bought the Tele from Thomann and after the stock strings got worn out I change them with a set of Ernie Ball. (When I was using Washburn electro guitar with Seymour Duncan and Dimarzio pickups with Roland Cube amp, I was using Ernie Ball 2223 009 strings and there was one unused set!)
Well, I can say that Ernie Ball worned out earlier than it was supposed to be regarding my earlier experience. Next week, I decided to put an order for new strings with another brand, and I chose Fernder's string for the first time.
After setting Fender guitar strings and playing the guitar for a couple of week, I could say Fender's string is more durable than the other one. These strings have smoother surface as well and did not loose it easily.
About the sound: I am not an expert on sound; I assume I can barely find the difference if I hear them (those 2 different brands' strings) by playing consecutively. But I can say Fender's strings sounds pretty good.
In conclusion, considering that both strings(this Fender string and Ernie Ball 2223) are nearly same price range, Fender's strings is the winner for me regarding durability.
