Do I have a loose strut? 

Hi.

I think I have a loose strut as I have checked everything else I can think of. I do tend to bash it as the cracks, all glued together (though not cleated), testify.

Could I ask how you would identify and fix the problem? I can buy a mirror and I have some glue. I made the guitar ('El Burdo') too so although not in any way a luthier I have a rough understanding. And obviously, no money...

I demo the problem here (recorded directly on Quicktime using AKG 1000S).



Thanks.

RE: Do I have a loose strut? (in reply to El Burdo

Doesn’t sound healthy.

It might be a loose strut, but I’ve also heard that kind of metallic rattling when a tuner is loose, so it’s worth checking that area out, too. You can start by tapping in the area of the headstock, as a rattle there might be pointing to the tuners. The problem with rattles, however, is it can be hard to pinpoint the origin just by listening, as the rattle can sometimes seem to be coming from more than one location at once.

If the tuners check out OK then you can start by applying pressure on the top and back over the locations of the various braces while plucking the string and see if the rattling stops or changes. Alternatively, take the strings off and tap around the guitar while listening for the rattle, then reach inside and hold the brace in question to see of the rattle stops.

Hope that helps, good luck and remember, everything can be fixed!

I havn´t listen to the example.
Just want to say that at times rattling can also be caused by lose strings end behind the bridge.

Hi RobF - it has pegs which of course are tight so I don't think the problem is there. I've pressed the top in a sort of unstructured way but it's not been precise. In fact, the buzz is not always there.

Ruphus - yes, I would look there but it's a 12 hole bridge and all the end bits are threaded through the adjacent loop so that's not the problem.

At least you hear the problem. Thanks.

Quite possibly yes. The rattle does resemble that of a snare drum. Tap lightly around the sound board to narrow the areas that should be investigated further. Once you have established which strut/struts are loose, get a piece of frsh paper and try and slide it under the lose struts corner first. Push it as far under as it will go so you have an idea of how much gluing you will need to do. Look with a mirror to get a visual.

From there I would awkwardly put quite a bit of glue on the paper that is on the otherside of the strut and pull it out. To clamp I use rare earth magnets. Or put something on the strut that is fairly heavy and leave the guitar on a neck rest front side down.

Hope that helps

Thanks Steve - that is a great idea with the paper, both as a measure and an applicator. I think I might try and stick a light source in there to help locate the struts a bit more directly too.

Check the nut and clearance at first freet too. I have a guitar that played well for years and then started buzz/rattling like crazy. Turns out the D string was touching the first fret, which I think may have popped up a little.

Hi Jim - I don't think there's a problem there as the problem is evident with a capo on. I played it in open position so that people didn't suggest it was the capo :-).

Well, I've bought some magnets (thanks Steve) but also a set of three sprung toilet roll holders as Dan Erlewine used them before he bought his $93 (each) scissor clamps. I think I've found the problem (thanks RobF) on the back struts.
