Have you (or anyone) tried analyzing this using ETD?  E.g. finding
the exact frequencies of the partials of each string and see what
coincides, what doesn't, etc.  Also perhaps measuring the relative
strengths of partials when all strings are played vs when individual
ones are played (using, for instance, Verituner spectrum display)?
