Hi Daniel - This is often caused by the string sticking in the nut. The tension builds up in the part of the string between the peg and the nut until there is enough to overcome the static friction - then the tension equalizes, usually at a level higher than you wanted. The sticking is also a cause of "pitch drift" - the tension in the two parts of the string is different and over minutes the string slips over the nut until the tensions are eqaulized.
Ultimate solution: take instrument to competant builder and have them check the groove, refile the notch or worst case make a new nut. Cheapo instant gratification solution: get a soft drawing pencil (2B or more works very well), push the string out of the groove and rub some graphite it. This frequently does the trick. ...........Bob -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
