Another thing I forgot, was last week I saw online (in a prescription channel) an interview with Sharon Isbin. She had recently tried out Scott Tenant's Antonius Muller double top, found that she could express her musical ideas better with the Antonius Muller double top than with her older guitar, a Thomas Humphries, an excellent solid top guitar, and thus purchased an Antonius Muller double top for herself. So this is the driver: when top performers decide they can express their musical ideas better with a newer sort of construction, that is what validates it, not because the luthiers want to make it. The lute is amenable to this construction because the tops are flat, and it will be up to some luthier to try it and for top performers to validate it.
BTW, I just ran across an interview with Gernot Wagner, one of the prominent luthiers of these instruments: [1]https://classicalguitarmagazine.com/gernot-wagner-the-master-luthier -on-the-double-top-movement-and-his-influences-2/?utm_source=Classical+ Guitar&utm_campaign�87c52354-CGN_RSS_EMAIL_CAMPAIGN&utm_medium=email&ut m_term=0_4fb5dcb616-b287c52354-361014909&mc_cid�87c52354&mc_eid8806f77a A.

Classical Guitarist/Lutenist On Mar 26, 2020, at 4:38 AM, Joachim Lüdtke <[2]jo.lued...@t-online.de> wrote: And what I simply forgot in my first mail on this topic: Among the newly built guitars shown and played during the guitar days at the Bremen Hochschule there actually was at least one with a Sandwich/Laminate/Double Top, plus there was one with a soundboard/barring construction following the principles and ideas of Steve Klein, but with a quite 'traditional' outline. That I personally could not make much difference between the instruments when played may have been due to my bad ear as much as to the fact, that one and the same woman played all the instruments to the people attending, and that this woman is known for her good, personal sound production on the guitar. In short: I suspect that she could have easily brought out different strengths and weaknisses of different instruments but seemed to rather bring the best out of them within the limits of a 'conventional' classic guitar sound spectrum. There also was a lecture by one of the young guitar builders who among other topics covered soundboard construction methods, including sandwich construction. At one point he summed it up with the words: "It all sounds guitar to me, and when it would not, it would alarm me." Joachim Thank you John, David, and everyone else who replied and contributed so far! My lute/guitar lexigraphy is quite a bit enriched now. As to the lute: I think I prefer the traditional construction and materials for the historic instrument.
