S&S D Duplex

[Sarah Fox]

Hi Paul,

I have the exact same question regarding my '33 Wissner concert, which is
very similar to the D.  There's a braid through the duplex from notes 36
through 52 but not in the upper range.  My guess is that the prior owner
and/or his tech thought the duplex sound was too harsh, perhaps in part
because the hammers (to be replaced soon) were/are hard as mallets.

I was also wondering about the tuning of the duplex scale in that note range
(the muted range).  Most of the duplex segments are tuned to sevenths, which
I figure are intended to resonate with the next lowest unisons.  Is this
normal?  The treble duplex is mostly octaves, which makes more sense to me.
Is that how the D's duplex is tuned?

Thanks for any advice from the list!

Peace,
Sarah
