JP, Of the many causes for wild strings, I've noticed that the most common around these here parts is faulty termination -- fortunately this is also the cause most amenable to quick correction. At the bridge end a bit of tapping down; at the capo end a little sidewise swipe or two and pulling up with string hook. Won't fix all by any means, but it'll help often enough before the concert -- and you can always come back later with the big hammer. Luck, Jim DeRocher
