I went to pick up new strings. Tired of the bad sounding Ernie ball I am going to go with DR again. I used a long time ago and stopped buying them for some reason. I ask the guy for 10s. He hands me one without asking me how many I wanted. So he had to get me 3 more. The GDFI gave me 11s. Since I did not have my reading glasses with me I assumed everything was fine. I got 1 set of 10s. (10-52) and 3 sets of 11s. Now I have to go back and fix it. He won't like it when I demand a dollar for the gas it took to go back. I'll let you know about that one. Sometimes I really hate that I'm going blind. At least I have one set to put on my guitar.
