"is it possible to make the pickup bright on the low string side and a little darker on the high side?"

You can:

-position the pickup in a tilted manner (closer to the bridge at the lower strings)

-get a peizo bridge and plop a tone control to each peizo transducer

-make a pickup that has a coil for each string, then use a tone control for each string's output.

A resistor is commonly made of carbon if being used for low wattage. Resistors reduce electrical pressure (voltage) and flow (current). These fixed resistors are very uncommon for unpowered guitar circuits, because there is no internal amplifier to bias. Variable resistors (potentiometers) are resistors that change resistance when you turn them, this is wiping a conductor across a phenolic wafer either closer to ground (more resistance) or closer to the output lug (less resistance). Values affect potentiometers ranges of resistance. If a potentiometer is coupled with a unipolar capacitor connected across one output and common (ground), it can cut high (it's a low pass filter [LPF]) frequencies at a variable amount. There is a breif explaination of resistors, pots, and how they apply to a guitar's tone cirucit.

A potentiometer cannot modulate the frequency, it is a variable resistor that resists electrical pressure and current at different intensities when it's wiper crosses the phenolic wafer. Such as in an octave pedal, the potentiometer can be used as a blend or intensity unit.

May not be your solution, but you can use a grounding from the wrist band and aligator clip it to the bridge. Or if it's a 2 prong power plug, use an alagator clip to connect the chassis to the screw on your mains wall plate.

Here's what you do, buy any stacked pot and pry the case off gently and replace the phenolic wafers and you can mix and match whichever wafers you need, in this case it will be 2 100 ohmers. Simple way to make a custom potentiometer.

I would suggest getting heatshrink tubing that can fit snugly over the wire and solder joint before you even heat it up. Especially if it's cheap, you could end up with heatshrink that barely shrinks, then it would still be adaquate.

My question is: Is the potentiometer linear (proportional phenolic wafer) or logarithmic (gradual)?

Ever try acetone?

Your bass looks gorgeous, awesome handy work bro. Does your neck go all the way to the pickup cavity? I can't wait to see this piece of artwork completed!

Can you get in trouble for copying an idea for personal use? This means to make a bass with the same specs as lets say a fender jazz bass and using it to play and not sell. This is a grey area, it's a bit confusing.

For grounding, you need to take these wires:

bridge/neck plate wire

pot case wires

jack - terminal lead

pickup negative leads

and solder them all to one common point, that's it.
