Buzzing more with higher tension

Hi All,

A guitar of mine, a Lazarides (model Reyes) buzzed a little too much for my taste. Using Addario EJ 46 hard tension.Frets where levelled out, and it is ok, buzzes still a bit, but it is low action, so ok.
Last week I tried for the first time medium (Addario EJ 45) strings, and it is a big differents, nearly no buzzing at all.

What happens here? The string hight is the same, 2.5 mm at 6th string.
I was always thinking that higher tension = less buzz…

Could it be, the sound wave, the amplitude wave, is on a different spot?

Oh, and, the top is quiet stiff, and the guitar have long sustain. 655mm.

Action at 2.5 mm calls for buzzing anyway. A properly worked fretboard and maybe a top on the stiff side can minimise the issue.
Logic tells us that high tension strings bend less than low tension and therefore the vibrational wave has less amplitude. In theory Nt strings should make less buzzing.
I guess the guitar may have less buzzing for a different humidity rate or other factors?

It is for me a riddle too. It is not the humidity I think, because putting on other strings takes 5 minutes.

The hard tension strings have a greater diameter, so they sit a tiny bit closer to the guitar and probably explain the buzz question. See the diameter specs here:

This can be a good idea; I had though to that also but eventually it's difficult to assess.
Some times HT strings do not seat very deep at the nut slots which goes towards minimising the difference in caliber; other times a little higher string tension goes towards a slight bending of the neck with higher tension which minimises again the difference . In my old Conde HT strings used to raise the action from 0.3 to 0.5 mm. to come back to normal with normal tension strings.
Obviously in your case, all these variables just don't happen.
I also thought the problem may not exactly a buzz but an odd resonance, but I can't assess it really.

Wow, that's crazy. Are you sure it was the strings? I recently posted a thread on hard tension strings and neck angle, and the consensus seemed to be the that the differences between normal, hard, and extra hard tensions were not sufficient to alter the neck angle unless there was an underlying structural issue.

Well, in this case it's just the neck bending a little + the top popping up a little more. This doesn't alter the neck angle as the effect stops with other strings.
Some old guitars are just more flexible as built lighter than today standards.

How would that be? It is their outer surface, not the geometric center, that sits on the saddle, and at the nut if anything they may sit higher in the slot due to their larger diameter but definitely not lower.

To the OP: Is it possible that you are trying habitually to displace the HT strings the same amount as the NT strings (which means you are using more effort), which in effect means you are playing the HT strings louder which somehow cancels any buzz-minimizing effect from the higher tension?

The only answer that makes sense to me is that you both attack and fret the guitar quite gently (it’s the only way I can prevent buzz on my own guitars that are lower than 3mm at 12). So the buzz with hard tension was from not fretting notes strong enough (especially barre chords versus single notes for example). That’s my best guess.

I hope you will pardon me for saying so, but I believe this is fallacious, since the bottom of the strings sit on the bottom of the nut slot and on the top of the saddle. Whatever you stretch between those two points will lie the same distance from the tops of the frets.

Exactly.

I stand corrected!
