I just ordered my first bulk order (12 sets) last week, and they came in First Class USPS in under three days. They were shipped in a approximately 8"x6" padded envelope, loosely coiled. There were seven long, narrow plastic bags that held twelve string per gauge, with the gauge clearly marked in large, bold numbers on each package. I'm still trying to figure out who makes these strings. They have brass colored ball ends, and the wound strings have the plain core leaders. I'm guessing D'addario, but without the color coded ball ends. With S&H, the total came to $48.57, or about four bucks a set. Knock out the $5.95 shipping, and it drops to $3.55/set, which isn't too shabby for a 7-string custom set. I went with 60-48-36-26-17-13-10. For me, the 48 low E is a good middle ground between standard and drop-D tunings. After stringing up, I noticed they are brighter than the GHS Boomers I am used to playing. Since I haven't used a set of D'addarios in years, I really have no clue what to listen for. They definately have way more attack than GHS or Dean Markley, which is what I had been using. They stretched out quick, and hold tune well. The ball ends are tightly wrapped, without the flop I have come to expect from Dean Markley. It's kind of hard to get excited about strings, but it seems like a good deal so far. I like being able to put together exactly the set that I want, and they are a few bucks cheaper than Guitar Center. Seems like a good deal so far, and I really appreciate the fast shipping.
