how they should look like...

a little bit of paint and alu foil and I have now a rough idea of how these guitars are going to look...

next step will be now to build the seven string (on the right) out of OSB.

you probably noticed that since the last post the 7-string has been reshaped, it's now more compact and closer to the original sketch ; still it's a quite special design, a good combination I think of ergonomic and aesthetic, with inputs from 'modern tradition' (Japanese style long lower horn, like the prodigious Tokai Humminbird reissued by Eastwood Guitars) and innovation.
the OSB model will show if this design is as comfortable as expected.
