I had a couple of problems with my A string, because it just kept breaking, so I decided to buy me a couple of A replacement strings. I had the Choice between Pyramid and Ddarrio, but I choosed the Pyramid because I swear on german quality. So I played some of them till I fixed my problem (It was something about the bridge) The sound is nice and clear and these strings last longer than the Ernie Balls i used to use. The price is also really fair and perfect for people like me. I think i´m going to buy a whole set of pyramid strings in future.
