David, The reason that it is so important to file equally and keep the tines balanced is that otherwise the central support will receive the imbalanced vibration and the energy will leak away from the fork at an alarming rate, giving you a very short sustain. You will still get only one frequency, but it will not be as stable as when the sustain was longer. -Bob Scott Ann Arbor, Michigan David Renaud wrote: With leads me to a question. I've purchased a fork with appears to have been adjusted in production at the base, filed on one side of the base only. and finished over. This was years ago, The Conductor of the local symphony made the comment, " it sounds like it has two sides". It was not beating, but he claimed it lacked "focus". So Is it important to file the inside base equally towards both tongs? If upon filing one side it still produces one frequency, perhaps it works harder to do so changing the timbre in some odd way?
