Effect of an anodized pickguard on pickup response

[marcello252]

I was playing around with my teles and suddendly I realized the most warm of mine on neck position is the one with the anodized pickguard , althought it has the same STR-1 I have in another one much brighter (both without cover), same strings, same pot and cap values.

Is it possible the pickguard had an effect on inductance? (I'm quite sure @freefrog , maximum worldwide expert of eddy currents and other for me mithological creatures, might have a graph or study about it )

Effect on inductance: not directly. Effect because of eddy currents: sure, it's possible.

I've repaired once a humbucker whose owner had swapped the baseplate for a thick aluminium plate (cause it was easy to cut and drill). How it affected the response of the coils was not less than spectacular, if memory serves me. Maybe I've somewhere a graph about that, I don't remember.

Further explanations there (point "B"):

For Tele Lovers

How would an aluminum bridge plate compare with other Tele bridge plates? To address this in detail would require some twenty pages of information ranging from classical to quantum mechanical functions! First, we must understand that the Tele bridge plate serves two totally different functions...

I was just kidding about the graph and stuff but you always amaze me with tons of useful information, thank you, really

Any large conductor inside the magnetic field of the pickup will dampen the amplitude of the resonance peak, aka cut treble, via eddy currents.

I would have said that it should be about as much as a humbucker cover, but I would believe it when somebody tells me the effect is more pronounced here. For example, the center of the magnetic field is right where the pickguard is with a rod magnet pickup like a Tele neck.
