This page is under construction, but this is the overal idea:
FM12: two 6-strings in one neck.
FM14: two 7-strings in one neck.
FM16: two 8-strings in one neck.
They are mostly headless, but "standard head" option is also possible.
The main body is the FM16 style (as you can see on the photo section) but we are also making bodies inspired on Tele, Strat, ES-335 and ES-175.
