Hi, I need help for this problem,... my new eub,... there is strange noise (tang like bell sound ?? ), when I was doing the tuning
then I found, that sound from the wood nut (maple) when rubbed by the string
is there a solution to this problem?
thank's a lot..

Tell the banjo player to shut up.

Make sure the nut is filed in the right angle so that its not to high on the tuner side causing a small gap on fret board side allowing it to viberate in the nut slot . I have had that issue before . can alose be caused if bridge is slot is not filed right . usally causes a buzz ....... dont know if that helps , but thats what I check first .

haha Casey,... that sound just when tuning,.. but no problemo when being played.

tomorrow I will check the nut angle and I will post the photo's.. is that need some oil for nut? for smooth friction? thank's

I have one that does that, coincidentally also with a maple nut I think the slot is just a bit too narrow, so next time I have the strings off I'll give it a couple swipes with a needle file. Also could just be a sharp edge that the windings are snagging on and then bumping over. Needle file would fix that too.

Oil would soak into maple, but you can use graphite (from a pencil) to lubricate nut slots. Usually not necessary, but doesn't hurt anything either.

The maple may be too soft, allowing the windings to leave ridges which catch when tuning.

If the maple is too soft and the problem keeps coming back after the file treatment, you may consider removing the nut, and putting a drop of CA in the slot, let it completely dry and harden and then touch up with the file. This should harden things up a bit, but it could cause some local discoloration, so test on another piece of similar maple first.

new found of strange sound exactly from the bridge saddle, maybe of the height of that construction,.. this is the photo and the web address:

this saddle buried in the cup of maple with black silicone sealent...
the actual string of this eub is like helicore string 4/4 but I use the 35" long scale GHS so I modified with add a tailpiece because my string too short, is that any problem?
the big problem (again) is the TANG ..TANG... SOUND when tighten the string...
thank you all...

Looks to me like the string doesn't break on the front of the saddle. That could cause the sound you describe, as the string will actually vibrate on the flat top of the saddle.

In other words, round over the front edge of the saddle so the string windings don't hang up.

Or file a string slot in back of saddle so it breaking on the front of the saddle instead of the back. Same result

beside file a string slot, is it necessary to lower the saddle and nut height? now string height at nut (E) 4.2mm, (G) 3.5mm and the end of fingerboard (26" from nut) (E) 6mm (G) 6mm... ???
thank's all friends...

I wouldn't file a slot, especially with that break angle, I'd round the top instead.

Exactly. I discovered that slotting a saddle can have a really bad effect on volume and tone. Not recommended.

Barry, is it necessary to lower the saddle and nut height? thank's

I can't tell you because I don't have the instrument in front of me for inspection. Lower the nut and or saddle if the string height warrants it. First, adjust the nut height first so that when you press the strings down at the 3rd fret that the string just barely clears the 1st fret. Then set the string action using the height of the saddle. I usually go as low as the neck allows but not too low to create buzzing. This is also assuming your neck relief has been adjusted properly before any of the action adjustments.

ok.. I see Barry ,... I'll try it,.. thank's a lot...
