I have an Ovation Celebrity CP247

How is the neck attached ? I mean is it glued or bolted or what ? Can it be removed and re-attached ?

The reason I ask is because I've recently started playing in some low open tunings (Leo Kottke etc) and when I get the bass droaning I get an annoying buz in the body of the guitar which I thought was a loose brace.

I've now tracked the buz down to where the top of the guitar is vibrating against the fingerboard. I have a gap there as shown in the pictures below.

The wad of BlueTac in the first picture stops the buzz happening (so please don't tell me it's fret buzz)






Although the gap looks huge in the image it's really only around 1mm at most and there's no gap at all on the other side of the neck. If I put a little pressure on the top of the guitar while playing the gap opens up a bit and the buzzing stops so I can see that the top isn't actually 'fixed' to the bottom of the fingerboard. Is it supposed to be ?

So I was wondering if the neck could be removed and put back on again. On the other hand it's just a 'celebrity' so the cost of having that done by a luthier would exceed the value of the guitar. On the other-other hand, it's a really nice guitar and I'm kind of attached to it.

The color, by the way, is 'Vintage Orange Quilt' and I've never seen another one like this.

Maybe I should just pour a bit of glue down the gap ?

Perhaps try wedging a small piece of thin plastic in there insted.

If the blutack fixes it why worry? You can take it out if you sell it and no damage done.
Just a thought.

I think they're bolted on, but I don't know if glue is also added. Several of the Elite models have a floating fretboard similar to that, but I hadn't seen one on a Celebrity. It's odd that the soundboard would vibrate so much that it would buzz against the bottom of the fretboard. Maybe there's something loose in there that you stop with the Bluetac.
You could remove the strings and back access panel and take off the bolts and see if the neck comes off. We have a few others that may have done that already. Check for posts by Old Man Arthur.

I'm pretty sure the Celebs have a standard glued dovetail-type neck joint. Not easy to remove and reset unless you know exactly what you're doing. Your own suggestion will work. Get some glue in the gap to secure the fingerboard extension and that'll cure the buzzing.

I'd defer to Paul. I just had another thought. Is the binding around the neck loose? You could be fixing that with the Bluetac.

I wonder what kind of glue would work. Cyto-acrylic thick from stew mac? Which would be permanent. Or a wood glue. Probably MWoody would know.

Thank you all for your comments.

All your comments are taken on-board

I'll be sure to come back and let you know what I did and how it worked out.

One final idea; try a little piece of folded stiff card and push this into the gap. Not as permanent as glue, but might work as a shock absorber (I think the Colonial term is damper but we know that means wet :) . If you're glueing, then I would try Aliphatic Resin; much easier to work with than cyano (Superglue); can be smoothed with wet tissue and can be washed off your fingers with water (before it's set obviously :) )

Here is what the neck-joint of a CS257 Celebrity looks like...

The innards of a CP might be similar...

And here is the thread... Might be helpful

I had a similar problem with an Adamas. In humid climates, the tip of the floating FB would curl down just enough to buzz on the top. I bought a sheet of thin felt from the craft department at Wally World and worked it between the FB and top.
Solved the problem nicely.

Again, thanks for all the excellent info.

That picture from OldManArthur/ElliotMeldoy is showing that the underside of the fingerboard should be stuck firmly onto the top face of the body all the way round.

On mine I think it's just stuck along the treble side.

You can see that the original glue was well inside the edge, but those are the pictures I was thinking of. Thanks, Arthur.

Thought I'd come back to let you know that the buzz has gone.

On the pictures posted by Old Man Arthur you can see that the 257 is glued.

On closer inspection of mine it looks as though there's a thin double sided adhesive shim sandwiched between the front panel and the underside of the fingerboard. I guess they're pressed together during assembly.

In my case they weren't pressed hense the gap and the fact that the front panel had a lot of movement in that area.

Anyway, I have some wood resin. In the UK it's made by Bostik, comes in a green tub, white stuff which dries clear, hard, strong but not brittle. I worked a ton of that into the gap all round. Made quite a mess but it's not solvent based so doesn't affect the gloss finish and excess wipes off with a damp cloth.

Job done.

So, once again, thanks to everyone who responded.

Thanks for the question and the info. This will help someone else down the road. Don't be a stranger.
