I strung up a set of Black Magic at 48x46 lbs after reading this thread and now have about 6 sets on it. Last night the stringbed suddenly changed. It has played comfortably since fresh but I thought I could feel it getting loose, then last night it seemed to tighten up and played firmer and a little more solid. Has anyone else experienced this with Black Magic ? I'm not sure if it has become "firmer" or if it has "settled" at a really low tension and that being a tension I haven't experienced before. Instead of cutting it I'm going to play it for awhile longer.
