VSWR "Voltage Standing Wave Ratio" is a term for reflection at an impedance-changing interface. I just think it's unlikely that you can magnetize part of a string enough to make this a measureable effect. | |

If the speed of these waves is not constant over the string I would have said that it would be possible… Taking for instance the extreme case of a string with half of it at a very diff gauge, this would behave as two different but coupled strings no? Part of the energy bouncing on the separation… | |

That part of your answer is partially inaccurate - if the magnetic transition is strong enough, one could view it as a VSWR at a material interface- but Im a bit skeptical that this is a real effect on real guitars. I think the undesired tonality is due to the described effects causing the "wrong" harmonic frequencies to be amplified more than we would like relative to the fundamental. | |
