I'm using 22 gauge wire for the electronics in my guitar, and I want to use a shielded two conductor for the jack. The only thing I can physically go pick up is 24 gauge. I can order 22 gauge, but it'll be a little more. How would 24 gauge affect the electronics?

Not at all. There is a tremendous load of hype floating aboot that there are "special magic wires" to be used in guitars.
If you want to have a vintage-correct guitar, you'll by the cloth covered wire and the vintage pickups just as you would by the crappy junk that went into cars in the 60's if you were restoring such.
I often wire the 4P5T super switches with a Teflon covered silver plated 22 gauge wire just because I have a fair amount of it from my days in the aerospace industry, and most certainly not because it's "special".
I also used insulated solid wire of 22 to 28 gauge because it stays in place while I'm soldering.
The typical pickup is wound with 42 to 44 gauge wire. Arc welding cables are not needed. Even 30 gauge wire is huge in comparison.
The typical scale factor of the American Wire gauge system is that a three count change in gauge relates to a doubling (or halving) of wire cross section and hence current carrying capability (and resistance). Each change (as in 22 to 23 gauge) is the third root of 2.
If you are using 24 gauge wire for hookup, and 44 gauge wire for the pickup coil winding, the difference is 20 "gauge steps".
This relates to a difference of 2^(20/3) or 2^6.67.
2^6.67 = 101.593667
Your hookup wire is 100 times the capacity of the coil winding. You'll be fine.
Note: There may be other issues such as the capacitance of the shielded wire, but for a foot or less, forget about it.

I once asked (elsewhere!!) about the use of shielded wire for hookup...with the idea that the shield itself could be simultaneously used to connect all the ground connections..(if you get what I mean)....like use it for ALL connections, multi-core shielded where appropriate, etc. I thought this idea might have some merit, in effectively screening all wiring.......the response was (elsewhere) rather ho-hum.....
....while it's a liiiittle off-topic, anyone (here!!) care to contribute their thoughts?.....:-)

Gumbo,
i don't think this is off-topic.
i see nothing wrong with using shielded cable throughout the guitar wiring.
it might be a bit overkill, but hey, better than "underkill".
i would be very conscious about ground loops, and only connect one end of the shield where appropriate, to eliminate redundant ground paths.
NanooMan,
the only thing "special" about the wiring in my guitars, is how it's installed, not the gauge or composition.

Thanks unk, barring the 'ground loop' thingo, I couldn't see a problem with it, but then you see sometimes I DO dream up some wierd things......like four mini-toggles, and an inbuilt GK2A as well..........maybe I SHOULD start another thread about that one ......!

ONLY FOUR! Dude, that's just a minor fling with obsessive (re)wiring dementia. aka the ToggleCaster under "Electronics and Wiring/Schematics" here-on

Yeah, I HAD seen that one.....thought maybe you guys had been playing with Photoshop.........:-)
