Unlike the tribute however, I'd make it with a solid body (unchambered). Also, the headstocks would be Alembic Crowns with the 12 string having the same spacing as the 6, so it would appear twice the length. Damn! What a cool guitar this would be!!!!
P.S. I recently tried an EDS-1275. What struck me most about it was it's INCREDIBLE sustain and resonance - with all that body mass. I can't put it down anymore. It really sounds great - gotta give respect where it's due.
