I think there are a variety of factors at play in terms of string stabilization. Yes, the wire does stretch. There is a degree of elasticity or "springiness" that has to be overcome before the string says to it's lovely metallic neighbors, "Okay, I'm all stretched out now". (How's that for drama?) Secondly, there are equalization points that have to settle. These include the curving through the bridge pins, the U-bend around the hitch pin, and the friction around the capo or agraff. If there is a duplex segment then there is yet another friction point to settle. Finally, the coil on the pin itself will snug up. I have replaced many-a-string and no matter how hard I try I just cant get the wire to make the perfect right angle into the pin hole. There is always this slight gap. Yet months later the becket is snuggled up nice and tight because the string formed itself around the bend all by itself over time. So there you have it, Rob's philosophical ramblings of string stability. Rob Goodale, RPT Las Vegas, NV >I sent this yesterday, but don't know if it went through.
