Default What makes the good guitar pickup sound so good?

Or why do the bad sound bad?
In electrical terms, I already know that magnet material does matter much.

I changed the spelling of the topic. I hope it is now how you wished.

Good and bad are way too vague terms to use as they will mean different things to different musicians and for different genres.

There are many variables that change the way a pickup sounds weather it be bad or good.

1. The magnet(s). Ceramic vs alnico etc and how strong they are or aren't

2. The wire. The quality of copper used and the thickness of the coating.

3. The winding. Machine wound bobbins or scatter wound (hand wound).
Also the number of turns has an impact. This changes the resistance value of the coil.

There are others but these are a few of the big ones.

It's mostly an art as to how one would combine the pros and cons of each variable to get the desired sound they are looking for

Hi and thaks for meaningful reply.
do you think that one could successfully affect the sound by adding external LC components? I think this might change the resonance frequency and quality.
And how about load impedance? Typically pickups are high-impedance loaded, like 500k potentiometer followed by high Z-in amplifier. Are there good reasons for that? How about zero impedance (short circuit current sensing) or something inbetween?

I think it is all Personal Taste...what sounds good to one person sounds awefull to someone else...

Case and Point:

I replaced the stock Les Paul Pickups in my epi Les Paul with a couple no name crap humbucker Pickups I got on e-bay for $3.50 each . after installing them the sound (for me) was 10 times better , much better chunkyier low end and really nice Highs that really cut through , the stock les paul pickups just sounded weak and dull....

I'm rather new to the reasons why things are the way they are with guitar wiring.

I do know that my active Duncan Blackouts in my 7 string came with 25k pots. I just don't know what the circuitry consists if since you would have to destroy them to take a look.

Looks like I need ti get back to the book store and Amazin for more resources as I would like to know also.

From what I suspect, there is a coil resistance, inductance and inter-winding capacitance, so a pickup creates a RLC resonance of frequency and quality dependant on R, L and C.
Does anyone have ideas on a nice ways to play with them?
Maybe negative resistance? or active inductance generator?
Anybody tried manipulating them like this?

Regards,
Adam
