I guess now I'm supposed to think my 594 is obsolete and run out to buy a new one
Wait about 20 years. Then, someone will have a hit song using an "old 594" before TCI pickups. Then your "VINTAGE" guitar will be worth 1 million dollars.
Right?
My 1 cent.
Tuned Capacitance Inductance are old radio engineering terms used to narrow in a specific Frequency/band width. As if you tune your 60s or 70's radio knob on your Am'FM radio. You are more than likely tuning a variable capacitor with air being the dielectric.
Oh wait...... you millennials don't know what I am talking about. Don't worry I am sure there is an App for it! LOL
If you look at Xc or Xl or any formulas to include "Q" type equations, along with mutual inductance equations, you can see how any one attribute variable will effect the equation. You need special equipment to measure inductance and magnetic fields and I assume Paul has everything he needs.
Don't forget a humbucker will have Series Mutual Inductance. A coil will induce a magnetic field into the other coil in a Humbucker. Yes, like a transformer. I am going back a bit to the 80's and college so I could be making all this up. LOL
Now how PRS specifically "tunes" their pickups is their secret. They probably measure certain components and adjust spacing, windings etc.. to end up with a certain Q.
For example: 2x10=20. Right? If you need the number "20" as an end result of an equation, then 1x20, 2x10, 4x5 all get you there.
Therefore, in theory, you can adjust parameters to compensate for other parameters. However, one parameter may be more musically sounding than the other.
For example, Fender used Chokes (an Inductor) to filter out 60 cycle hum in their amps. Today, people use resistors as part of the circuit (as in Mesa Boogies, any modern amp, etc.). Resistors are cheaper. However, it all depends on the engineering, parts, and what end result the engineer and sales department can agree to.
BTW - this line of "theory" is what got Fender in trouble with their amps when CBS took them over. The theory and physics may be correct electrically but it may not be "musical" sounding. Tubes vs Transistors? Modeling? Class D amps?
Well I hope this helps out a bit.
