Hey guys, I just got back from my local music store to purchase a new set of strings (Ernie Ball Cobalt Slinky 5's), and was so eager to try these things out since I've heard such great things. Well, I start stringing it up, and when I get to A (.80), well, there wasn't one in the package. Everything else was there B E D G, but A was absent. This is my first set of EB bass strings, though I've been buying their guitar strings for years. I have never come across this before. With strings this freakin' big, you'd think it'd be pretty hard to miss one of these things in the packaging process. Not sure if these are packed by hand or by machine, but maybe someone thought they were packing 4's. Anyone ever had this happen before?
