Technically it doesn't matter but conventionally it would be in the hot side so that goes: hot wire->resistor->EL strip->neutral wire.

As for the math, it's just Ohm's Law and Watt's Law. Here is a...

You mean wiring the pickups directly to the jack with no volume or tone controls?

Sure you could do that but with no pots to load the circuit your sound will be noticeably brighter and a bit louder.

Pot value doesn't affect bass frequencies, so no. And. 022 is the fender value. .047 is the typical humbuckers value. I think it has to do with the inductance of the pickup but it really doesn't...

Fender-style pickguards are like fingerprints. The only one that will ever line up perfectly is the one that came with the guitar. :rolleyes:

Higher pot values load the signal less so more highs stay in the signal. The effect isn't that drastic but it is noticable. You'll probably want to use 500k because 250k makes the humbuckers sound...

Sounds like a loose solder joint, not necessarily a ground issue.

You'll have to open it up and check the board for shoddy solder joints. This is best done under bright light and high magnification....

You can just snip the wires if you are removing them. You won't have to rewire anything. Tone pots are wired across the signal path.

A push-pull pot is just a normal pot and normal DPDT switch combined into one device so that they can be controlled with the same shaft. They are otherwise totally independent. Know what i mean?

The wires to the jack are backward. It looks like the push-pulls are just coil-cut switches. Also the tone knob appears to only work in the 2, 3, and 4 positions according to how you drew the diagram.

Lower pot values load the signal more heavily, causing a noticeable decrease in high freqs. They most certainly affect tone. Most people use 500k for humbuckers. IMHO 250k is way too dark and 1M is...

20 gauge (or 20awg) is a tad big for pedals. 22awg is better; its smaller and fits the solder lugs and PCB holes much better.
