Re: bridge plate and Base plates Magnetized?

In TDPRI: the Tele forum, there are a lot of posts about people swapping out the bridge plate and installing brass saddles. One interesting post said their tone got far better after taking off the plate then refixing it, firmer/tighter. Stands to reason that vibrations are then transmitted better through to the guitar body. Similar posts about hammering the plate totally flat before fixing it.
Brass saddles seem to make a difference, but then also no two identical guitars sound the same. this is important. Every one will have differences in wood, construction, grain density, etc. that will make their tonal response different. I believe this has far more effect than any contribution some weak residual magnetism of a bridge plate may have. Think how weak and dispersed any magnetic field will be compared to the focussed field of the pickup poles directly under the strings. I cannot see how this can make any difference to the tone. It's a physical transmission of vibrations thing, not a magnetic field thing.
The magnet field, I think, might have a bigger impact than you realize. I am, of course, not comparing two different guitars. If you have the chance, get yourself a metal HB mounting ring. And check out the results in the very same guitar. I know I did and it really did change the overall nature of the tone. For worse!
The way it does change the tone is the following. Without any magnetic material around, the magnetic field covers the strings in the way it is supposed to. But if you were to use a metal mounting ring, or HB routed tele bridge, the metal around catches some of the magnetic field. I saw magnetic field graphs done by Steven Kersting to that regard. In his email he showed me those graphs he had done (he loves these magnetic field graphs!!!) without any comments.
The same principle works for the difference between slug pieces / screws design versus dual allen heads design. If I remember right Zhang did lotsa experimentation with the length of the screws on PAF kinda buckers. I've not done it, still, if I remember right, when shortening the screws, the magnetic field will be reflected more upwards (towards the strings), thus, mid become more snappy,...
Anyway, the following claim, thus, is simply NOT correct "It's a physical transmission of vibrations thing, not a magnetic field thing". It involves a combination of both.
