String near last plate strut in treble doesn't want to stay in tune while I'm tuning. </FONT></DIV> <DIV><FONT face=Arial size=2>I checked the wire for possible trouble and couldn't see anything obvious, except the routing seemed a little crooked. So I straightened out the wire routing, seated sting  lightly on bridge, eased the rounded areas of the wire at the capo, and made sure the tail was seated at hitch pin. Pulled string to pitch and all seemed well. I congratulated myself and proceeded to make out a bill. While waiting I rechecked the note in question, and, the right string was back out of tune again. Ok, I said to myself, I must not have gotten nearly enough stretch out of the wire or something, so I whammed it into tune once again.
