    when wiring up a telecaster w/ a humbucker in the neck and a single coil in the bridge using a 500k volume pot they recommend a resistor to make the single coil see a 250k. one of the suggested resistors is 470k to get near 250k. if you use a smaller resistor say 220k does the pickup see say a 770k or 280k or what? lol

    i'm trying to get a little more high end that what i have which is the reason for the question...

    a 470K resistor in parallel with the 500k pot, will allow the pickup to "see" approximately 250K.

    I'm guessing the this added resistor is in parallel with the Pot? If so just use parallel resistance calculation. For 2 resistors it's (R1*R2)/(R1+R2).

    so a 220k or 330k resistor will effectively have the pickup seeing what?

    one of the diagrams has the resistor on the end of the pickup lead then into the switch
    another diagram has it on the switch and then to the back of the volume pot
    confused, lol

    thanks for the help

    We would really need to see your wiring diagram or schematic to understand where this resistor is being inserted into the circuit. If it is just inserted across the pickup leads then it would follow the below scenario.

    Resistance of pickup signal output to ground with the volume pot turned all the way up:

    500K || infinite ohms (your stock situation) = 500K ;minimal signal bled to ground. hot and bright
    500K || 470K = 242K ;very close to normal fender S.C. pot value. typcal tone that the pickup was designed for.
    500K || 330K = 198K ; more signal bled to gound. less output and less bright than normal
    500K || 220K = 152K ; even more signal bled to ground. possible mud territory for a pickup

    Just try a few different values and choose your preference. Can't really hurt anything. If a tele bridge s.c. pickup isn't already bright enough using just 500K pots, then you have a pickup that is very warm voiced or you need to have your hearing tested. Most tele pickups would be super ice picky with 500K pots.

    You could always pick up a Fender 375K pot, like the one that they use in the '52 HotRod Tele. Or try a 510K Ohm resistor, which would be close to 252K with the 500k pot.

    (1/500 + 1/470)^-1 = 242.3
