I was examining my Elite LX the other day and noticed the soundboard is not perfectly flat. The back end of the bridge looks higher than the front.

Is this normal? I'll see if I can capture what I'm trying to describe with a camera tonight.

Thoughts?

No way I could be 2 for 2 so I will just keep my mouth shut and let some other expert guide you.

A couple of years ago, my Balladeer started to do the same thing. It was in the winter. I took it to someone "in the know", and he said that the guitar was very dry and to put it in the case with a humidifier, making sure that the humidifier is always moist. I did exactly as instructed, and it went back to normal.

That is usually fixed with a device called a bridge doctor. you can find them at stewmac.com.
I made one myself using oak and a very long carriage bolt. but then again I was putting in a $40.00 dollar guitar.

Make sure it's humidified...

but, if the action is good and there is no separation tween the bridge and the soundboard, it's argued by some reputable luthiers that- that development produces better tone as there more efficient transfer of vibration from the strings to the front of the bridge, where nearly ALL the sound is actually generated...

The tension of the strings pulls at the bridge placing he fulcrum at the front of the bridge -- it is there that the greatest vibrational transference occurs.... the situation depicted above actually increased the efficiency of this transfer according to Roger Simonoff and Dan Erliwine.

In fact, I believe that someone posted an article or even video demonstrating this concept....

Hi, one of my guitar show same "dome". Hereinafter what I found at "FRETT.COM" :
Quote
.....Well, it is possible that you have some real trouble there. In a healthy guitar, the "bulge" behind the bridge usually takes the form of an overall "dome" rather than having a lumpy appearance when viewed in reflected light. Now, sometimes the bracing inside simply "translates" through the top to reveal the location of brace ends, where there's no damage or difficulty. Where there is a pronounced "wrinkle" in the top behind the bridge, it's often a sign that the top has become loose from the X-brace in that area. As far as I know, there is only one cause of this looseness: excessive heat......

This guitar is well taken care of and is less than 3 years old. It's never in excessive heat or cold. I do not have a humidifier going, but I can imagine anything in this state drying up. My freekin' car grows moss on it if I don't wash it occasionally!

It's an Elite LX.

Would this be a warranty issue? Maybe a ship to Ovation is in order?

Actually I just re-read everything.

So the "mound" can be normal and may even be designed that way?

Does anyone else have one like mine that they can look at? If it's a standard thing, I don't want to send it off.

I'd miss it! :(

My 6778LX has a slight mound behind the bridge. You really have to look for it to see it.
