I know this subject hasn't attracted a lot of interest here, but gotta tell ya, I've been pleasantly surprised by responses I've gotten about this idea from some great guitar makers.CF Martin's, Dick Boak - UK based world class luthier Stefan Sobell - and US based fretted instrument builder and repairman, Frank Ford (at frets.com) all found the idea appealing and wrote back with some positive feedback.
Our own Mudcatters; Seamus Kennedy, Terapln and then a few folks I don't know have also sent me some comments. I guess the idea of the small bodied, alternate tuned, music box has a lot of appeal.
Martin sent a response that is posted in answer to the original article.
