Eliminated a sitar-like tone to guitar. Questions remain ...
Does the sitar-like tone come from slots too deep or not enough string angle off the nut? Or is it a pinched string within the slot?
I just finished a $10 junker with a cracked headstock which wanted a new nut, and I got the sitar-tone. Filed the nut top lower so the string sits proud, and extended the slot to make the string break off the nut sooner and at a greater angle. And maybe widened the G slot a little. But is there a definitive single cause for that sitar-like tone you get from an ill-adjusted nut? Can the tone come from other causes? Loose brace, perhaps? I recall a faint note distortion on a cello caused by the tiniest back-to-side separation. That's what made me think of the brace (and look for it, after initial nut remediation did not correct the tone issue). |

String is touching something whilst it's vibrating, possibly the nut.

What I was questioning was what particular issue caused the distorted vibration. apparently a combination of issues can cause the distortion. As best as I can figure, guided by a thoughtful PM *THANKS*, the top of the string slot was level instead of angled, which I fixed early on. There may also have been string pinching; I measured the strings with caliper and used the right slot files, so hard to tell on that. The other issue, which I *think* leads to a muffled string, is a slot that is too deep. I've worked the nut so that the strings sit proud. Do I want, in the perfect world, to have my angled string slot pointed at its tuner? |

There are a number of things that can cause a sitar-like sound. If you are certain that it is nut related, here are a few things you can check.
First, ensure that the string breaks over the leading edge of the nut - at the face of the nut against the fingerboard. If not, not only can intonation be affected, but it can cause a buzzing sound. This includes ensuring that the slot is not damaged or chipped at the leading edge of the nut. Second, check whether or not the sitar-like sound occurs only with open strings. If not, it isn't likely the nut. That is, if you get the sitar-like sound only while playing the open string, then fret the string and the sound goes away, then it is likely a nut issue. If it buzzes only while open, the nut slot may be too deep and the string, when vibrating, might be grazing the top of the first fret, causing the sitar-like sound. If it buzzes while fretting up the neck, do a search on "back buzz": you'll find lots of information on it and how to remedy it. Third, a deep nut slot will not cause a string to buzz. It is largely for aesthetic reasons that people choose to minimize the amount by which the string is "sunk" into the nut slot. (Not having huge amounts of unnecessary nut height, can "get it out of the way" of the player.) Conversely, if the nut slot is too shallow, perhaps much less than half of the string diameter in the slot, it is possible for the string to be insufficiently supported and it might vibrate side to side across the top of the nut, causing a buzzing sound. Having the nut slots "aimed" towards their respective tuner pegs is irrelevant. Some do it because they like the aesthetic or because they believe it reduces friction at the nut. |

Here's a guitar designed to sound like a sitar.
