Interesting (and fun) videos, Keith
For me the real question is: When does really compressed cardboard become MDF/wood substitute? You can apparently make guitars out of anything, if you can make it rigid enough and cut it. The hook here is in the word cardboard, which everyone associates with weak/floppy
Do you think they are the same guitar? They look identical apart from the logo on the scratch plate
The thing that intrigues me is the number of, apparent, holes in the thing. Are they really as they look, or have they filled with with some sort of clear epoxy. In which case it’s a rigid polymer guitar with cardboard encased in it.
However, the discussion seems to suggest that is not the case, although I expect there’s a fair bit of epoxy in there regardless. Not least, the comments on how light it is suggests there’s more cardboard than epoxy. And it certainly doesn’t look like all those holes are filled with much.
Either way, I can’t see the structure being particularly “resonant”.
I’m also intrigued how they got the neck strength. They glossed over that in the videos. Clearly it has a truss rod, but how did they get the strength at the neck joint?
I didn’t see any evidence of epoxy in the build.
I think the essence is in compressing the ‘cardboard’ (probably with some kind of chemical bonding agent) to get it super strong so you can form the honeycomb structures lending it the strength.
You can hear it sounds like wood when the neck/headstock hit the counter.
Yes, they call it FSC Certified Richlite. And bodies of the cheaper series are made of HPL (High Pressure Laminate/sounds way better than I thought) .They say, one argument for the fretboards is that they are more evenly in structure as wood and have no deadspots. (Didn’t see the videos above yet.)
