This 10-string guitar is quite uncommon. Its "double-neck" features a fretted 6-string fingerboard plus a supporting "stick" for the 4 bass strings, and is detachable (and adjustable, of course). Inside the box, between the heel and the end block runs an adjustable iron "compression bar". Another even more uncommon feature is a second, heavily cupped bottom of laminated wood which gets screwed on the rim of the "real" bottom. The purpose of this second bottom is obviously to let the first bottom vibrate freely while playing the guitar with a strap. The second bottom touches the guitar body only via a few felt lined "feet" in order that no second air chamber is created between the two bottoms.
The plan comes in three sheets (1:1 scale of course) plus a CD-ROM with about 50 photos and closeups.
Every of the three sheets display (I guess all of) the details of this very unusual guitar, and every sheet features some colour prints of detail photos of the guitar.
We owe the existence of this plan to the guitar's actual owner Matanya Ophee who commissioned the plan to the luthier Gary Demos an sells it now under his own publishing company Editions Orphée (manly sheet music) .
Here you can read some more info about the history of this guitar. There is also a "add to cart" button which redirects you to the shop website where you have to hit another button named "add to basket". But in the end it works. My plan arrived within less than a week.
Visiting Gary Demos' website you learn that this guitar is "magical" ... and also can see a preview of three partial views of the plan plus a link to Matanya Ophee's website for those who want to buy the plan.
Side note, slightly off-topic, or whatever:
Matanya Ophee is a really amazing guy with a tremendously interesting life. This post about the plan would not be complete without saying that it is well worth the time to visit some other (text-heavy) parts of Matanya's website where you get some insight in his life as (classical) guitar addict, airliner pilot, and finally music researcher and important editor in the latter field.
Below some links to samples of his websites which not only give an insight to his meticulous working methods regarding musicological research but also are testimony of Matanya's vivid internet activity through the last years (he got 80 in June 2012).
A few lists with links to his articles, here two of them:
- Liner Notes Musicology
- On the dangers in publishing music that is in the public domain
