[CAUT] pre-stretching new string?

[Bob Hohf]

I've been following this discussion with some interest, and don't have any
strong opinions or data on one side or the other of the soundboard/bridge
debate.  However, I'd be interested in how the various factions explain the
difference in humidity-related pitch change between the treble and bass
bridges.  We've all observed the same sort of difference with both
solid-body and cantilevered bridges, so I don't think it can be explained by
simply saying, "Bass bridges have more wood, so they expand and contract
more."  And how about those Yamaha C3s where the lowest octave of the tenor
bridge has far greater seasonal pitch swings than any other part of the
scale, treble or bass?  

Just wondering
