The "suspect in question" does in fact drop in to the Fender nut slot and then the shelves lean over or rest on top of the fingerboard. I haven't seen the acoustic ones yet, nor the one I ordered for my Epi Night Hawk.
In Nashville they call (or perhaps used to) these kind of intonated nuts
" shelved". Some of the nut slots are also cut back further into the nut body, by the way.
My acoustic guitars, especially the 12 strings, got louder once I had these nuts made. I theorized that it was because the strings were more in tune with each other ( the octaves) and in better sympathy, harmonically. A friend who also had his guitars and bass done, and I both noticed we were using less EQ on tracks with these instruments and that they blended better- more readily. I am used to it now after 13 years, and want to do it to my new guitars and basses (baritone, and mandolin). This will be my first Earvana experience, though I have tried all the Feiten guitars run across in shops.
RE butchered guitars; I've been asked to fix some that didn't "deserve" to be repaired. As a guitar teacher, I would be exposed to some very creative "fixery" and be asked if they (the student-to-be) could learn on this "guitar shaped" object-clunker-turd. LOL
