Noisy Yamaha Strings

[ed440 at mindspring.com]

A sound in the vicinity of the 13th, 15th or 17th partial that does not change pitch as you change the pitch of the string is probably a longitudinal mode.

Arledge is the only string maker who really tries to deal with this.  If he makes a string that produces a bad longitudinal mode sound, send it back and he will redesign and replace it at no charge.

>    Good Morning: A new customer has a Yamaha GC1 that has some noisy bass strings. That is, these strings have a very prominent high harmonic that stands out and is very unmusical. For example, the left unison of C#2 has this problem, but the right unison has it only to a very slight degree. String settling did nothing, and voicing only quieted the string down some, but did not eliminate it. Greg at Yamaha Tech support would only say that this is a characteristic of Yamaha strings and is not considered a manufacturing defect, therefore is not covered by the warranty. So he suggested the customer spring for some Arledge or Mapes strings, at her cost. Any one have a better idea?
