Thanks for sharing the video. Really neat to hear the different woods back to back like that. With the volume you're building you must get a good feel for the differences.
I'm really fascinated by this revelator design, I hadn't heard of it prior to joining this forum and finding your facebook page a few weeks ago. Have you ever shared any details on the structure? It seems to have such great tone and volume for what looks like a very thin body. What a surprise to hear how it sounds. Is it built up from bent sides and braced top and back like a traditional acoustic instrument? Or does it have a thicker unbraced top and back/sides hollowed out from a solid piece and as you'd do with a semi hollow electric?
Editing to add - I found an older video on your facebook page that answered most of my questions. Just want to say again, this is a really interesting design. Probably the most creative small acoustic design I've ever seen. Really great stuff, thank you for sharing.
