What you hear when playing is not what the audience hears, as the sound is coming from below your ears and moving away from you. In a damped room/studio, you get very little reflected sound. Also, arco players always get more volume from bowing a string, but it also affects the harmonics as the string is being mechanically manipulated constantly by the bow hairs and therefore the string cannot develop it's own overtones as well as it can when plucked once and is then free to vibrate as it wants to. This then accounts for the perceptions people here talk about when playing Pizz, or Arco. As far as break-in is concerned, I have observed that a set of 3885.0W strings drop off noticeably, played or left sitting, in the first week. The overtones, volume, growl and brightness all taper off the most in the first 48 hours. They still remain, put as time goes on, you have to play them harder to to get them to respond like they did when new. My 3885.0W set was installed almost a year ago, I play Pizz mostly, some arco on occasion, and practice about 1-2 hours daily, with a 1-2 hour performance every week. Lemur had to adjust the soundpost when my bridge had been bumped and was reset, and that actually revived the strings for about 3 months before they began to drop off. All of this is my player's point of view perception, but my fellow musicians and the audience say they think the bass sounds great. I asked everyone when I got the new Spiros if they could tell by what they heard; Only the guitarist really noticed and said they sounded richer, but not louder, just more defined.
