One time, playing a 5 nighter in Halifax, Canada, I went to the local music shop for some strings before the gig. I normally get D'Addario XL's, but the dude (well respected musician) recommended these Dean Markley Elixers (they were a brand new product at that time) and swore that they would hold their brightness for a good long time. I was hesitant, the strings were $110 per pack, but I though, why not.... I get on stage that night, E string snapped 2nd song in the first set, and I didn't own a second bass at the time.. Of course, I took them back, got my money back for them, and bought what I always get, no problems.. Anyone else have a similar experience?
