[CAUT] back duplex

[Richard West]

---------------------- multipart/alternative attachment
I would be interested knowing if aliquot placement has a bearing on 
bearing and therefore on this problem.  It seems to me that moving 
aliquots closer or farther away from the bridge not only affects the 
pitch of the duplex part of the string, but has some affect on 
downbearing.  I've never done any research on this, but perhaps someone 
has and could shed some light on the aliquot/downbearing relationship.
