I had standard tension strings on my guitar and replaced the D one with a high tension one, which greatly reduces the buzz. I do prefer low tension strings on that guitar but will I have to deal with bying two sets of strings (one high and one normal tension) to get rid of the buzz ?
A part of string buzzing on the 4th string has to do with the frequencies (as on the 6th!), most guitar have basic and other resonances within F, F#,G and G#. In this range the string acts in a different way, and the resonance response of the instrument will add an excess of excitement. This brings the string in a chaotic vibration which has more amplitude
than it would have in another frequency. In this case you are playing in the lower positions and this is exactly where distance between fret and string is smallest. To solve the problem : higher setup, higher string tension, playing techniques to avoid the buzz, local fret leveling in a specific sector of the fret board to add some space for string oscillation for certain notes. There are also some chaotic resonances, with vibration feedback thru the fret board – this happens most often with very new strings and when you are not pressing the string really close to the fret. This happens most often with 2. and 3. position the 4th string and only on some instruments.
