I have a Flying V that is too bright. I've tried 3 sets of pickups in it and all are too bright. They are too trebly sounding.
A common remedy for too much treble is to use a lower resistance pot in place of a higher resistance one. The lower the pot resistance, the less treble gets passed though it to the amp. 300K is a common lower value pot.

Here we have a CTS brand pot rated at 500K resistance.
|
|
It's actual resistance value is 488K. This is normal. I've never had a 500K pot out of the bag that really was 500K. Some are lower and some are higher. Thats just the way of the potentiometer.
|
|
The trick to decreasing a pot's value is to combine a resitor to it.
Here is a 750K resistor. Using this value we will change the pot to 300K.
|
|
The resistor can be attached to the pot two ways. On top, or on bottom. |
|
Here I've attached the resistor to the top of the pot.
|
|
And the new resistance value is 295K.
|
|
So,
500k & 750K = 300K
Combining resistors with different values will change the pot respectivley. For instance, a 1M resistor will change a 500K pot to about 330K. A 500K resistor will change a pot to about 250K.

To figure out what combinations of pot and resistor will produce a specific value you can either
use this formula: R1ŚR2/(R1+R2)
-or-
use this software: Electonics Assistant
