Now THAT'S what I'm talking about!!!  
 

As you see, the shape of the area between the horns and neck are slightly altered but the basic shape of the body is intact.
Only aprox. 18% wider.  
 
There is a risk that the pegheads are too close with this design.
But twist the left horn out, and squeeze the electronics together slightly,
then the necks can be set a little further apart.

The tailpiece will be about 27 mm lower than on the picture, due to difference in scale (25.5 - 30).
That is with the end of the fretboard in the same location.

I think the necks are a little too close.  The body looks great though.  The Gibson is a useful example for proportion and neck angle.

I found these pictures on Ebay of a one off custom EDS-1275.    

 

 

  I suppose that this configuration makes sense if you play with different tunings.  Interesting though.

Rob,
 
many thanks for the great work you have done.
This looks really great.

Oliver,
 
Are you actually going to build it?
 
That's one Featured Custom article I'd look forward to reading.
 

I can only imagine what Rob's commission will be....    
Amazing work!

Rami,
well I need to think on how to finance this beast.
Eastcoast,
:-)

How would that balance with such a short upper horn?  
 
Cosmetically, could you lengthen it?

What if we all send you $5?  I'd do it if it would help start seeing this thing come to life.  I've really enjoyed following this thread. - Mike

I have an idea:  How about if we get an official quote from Alembic, divide the cost of building it among us, then have a draw and one of us would win it. We'd need a minimum number of entries to make participating attractive.  If it's going to cost around $20,000 (for example) we should have at least 200 people willing to contribute $100.  The more people participating, the less the contribution.  500 people would contribute $40, 1000 people would contribute $20 and so on.  
Still better odds than a lottery!
 

Maybe that's not such a good idea for such a personal instrument - Oliver may not appreciate seeing his baby with someone else, but perhaps we can all pitch in and design an Alembic that incorporates ideas from all the club members.

You mean something like a club member special edition annual raffle? Sounds way too intriguing!
We would have to work out how payment gets to the mothership prior to the build. Perhaps enlisting the help of their network of dealers?
I would enjoy a chance at custom Alembic ownership for a fraction of the cost!
