Location: undisclosed		A traditional lute back is made like that using thin strips over a mold edge glued together. Parchment is then glued to the inside for reinforcement. Something like dynel instead would be stronger. The main trick on a guitar bowl will be laying out or spiling the "plank" shapes to make the waist, A lute can use the same shape for the pieces.

The DY-92 was actually a wood vaulted-back guitar made in the method you describe. Not too sure about the parchment, though.

The Ovation is a fiberglass vaulted-back guitar.

This photo give a good idea of how I'm going to build mine.

The vaulted-back guitar was the transitional design between the traditional lute-back (potato bug) and the 'flat' backed guitar we know today. (See: Vaulted Back Guitars)

Location: Boise, Idaho		We circulated a wood backed Ovation knockoff that Jeff W. bought over in Southeast Asia. It probably took a fair amount of hand crafting, but it didn't sound all that good. It was a shallow bowl and just didn't resonate that much.

Location: Pueblo West, CO		I've got some torrefied Adi spruce I'm saving for the wood-backed O-clone.

I'd really like to track down some torrefied Adi to use for the braces.

Location: undisclosed		Interesting link on the vaulted back pictures. It looks fairly straight forward laying the strips like that. Cutting the ribs out and shaping in stacks could save some time.

Ovation must have liked the name, too. The original Vipers were a solid body guitar with a 24 fret to the body neck. Skinny at the nut, with 2 special pickups that make it sound sort of like a Telecaster. The Viper III had 3 pickups and are pretty rare. The second Vipers are the ones you are looking at and the third are the f hole ones they did recently, for an artist whose name I can't spell.


I'm not sure of the whole story, but the body shape, as in the outline of the top, are essentially the same on all the Vipers (solidbody and chambered) hence the name being the same.  The lower horn is a little pointier on the new ones.

Here's the back side Nancy...

 

 

And here's an unfinished body...

 



WHOA!!!!!!

Wait a Minute!!!

I didn't understand what Patch meant when he said that the strings went through the body to the back....
I just looked at the pictures of the Vipers again, and THE STRINGS GO THROUGH THE BODY TO THE BACK!!!!!!!!

What is the reasoning/logic/thought process for this??? This is Fascinating!!!

(Sometimes it takes a couple of weeks for a question in "The Queue" to come to the front to be asked!)

Location: The Great Pacific Northwest		Mind you I don't actually know the answer why they are string-thru ('cept the Nylon EA-63's aren't string thru) but I have a few guesses. The first being that it takes the pressure off the bridge of having to be both the sting support AND the bridge. With string through, bridge barely needs to be glued in place as the strings will hold it there. There may be some transference of the string vibration to the body which may enhance the tone a bit, or maybe the idea is to get the ball ends as far away from the pickup so it sounds more "acoustic" than "electric". Or it could be a combination of the above. I will say it makes changing strings a breeze. It's certainly not unique to Ovation. Many electric or semi-hollow guitars are string-thru-body.

Location: Frozen Tundra of Minnesota		Thank You Miles!

That is Amazing!! I have never seen that before, and once I put what Patch said together with Damon's picture, it blew me away!! WOW!!!!!!!!

---So... do they use String Tubes to go through the body to the bridge???

Mr. Ovation - 2015-12-22 5:48 AM  Many electric or semi-hollow guitars are string-thru-body.

I think the first and most widely known guitar with string-through body is the Fender Stratocaster, built since about 1954.

It's my opinion that the string through body design adds to the sustain/tone of these nifty guitars.

Location: Frozen Tundra of Minnesota		What a Beautiful Guitar Jonmark!!!

Thank you for sharing! I am fascinated by this concept, how would someone even come up with this, and reason that it would improve the tone and sustain? I would LOVE to see one of these up close and personal, and see how this is done. Thank you Damon for posting the blank picture, and back!!!

I can't wait to see the new REO one coming out, but I would really like to see one taken apart to see how everything works! . (Don't let me by your mechanical things, I love to take things apart to see how they work, but always end up with spare parts later...)

Location: undisclosed		You should research Leo Fender, he was a true innovator and paved the road for solidbody guitars. Just don't blame him for what happened in O town, it was long past when he sold the company.

Location: moline,illinois		I don't think theres a new REO guitar,the ones from the factory tour were probably there for some TLC from john budny,if you look at the pics there are tags on the cases for repair/return authorization.If you look at any REO concerts from the past few years kevin is paying a custom viper on stage.
