I am interested in knowing the history and spec's of this beautiful bass.
 

It might take a while to get the specs from the file, but I'm pretty sure this is the bass I'm using in this month's special to demonstrate adding custom features to an Essence. It's a really beautiful instrument.

Steve, the spec sheet for this bass is online at Icon guitars.  You linked to it in your For Sale listing.  I don't think Mica is going to be able to give you any more information than a copy of that piece of paper.

Here is a picture of the wood card from another thread: http://club.alembicguitars.net/Images/395/64011.html
