One of the more effective solutions for dirty electricity in the wires are probably Stetzerizer filters.
I think they are just expensive capacitors taking off dirty electricity spiking, but AFAIK they do have a good name (in the alternative health world at least) and other solutions would be more expensive and more "out there" if you are a mainstream science type
There are solutions for most things nowadays, but not always easy, cheap or "scientifically proven" yet.
Worst case: to make a small spot where you can play should be possible in any case, I'd hope.
A Furman, idk. You may get lucky or buy the "$1000" one and still not be helped.
Which in your case is what I'm afraid of, as we seem to agree it's probably coming through the air and picked up by the guitar.
In any case, Stetzerizers also make your house much healthier, cos this dirty electricity is probably reaching you through the walls meters into your space. So for me they are a no-brainer (I still wanna get some European versions of them myself).
If the source is something else (as we think), there are probably solutions too. I have some books or guys I could ask maybe. This info is becoming more and more popular and important because it's all around us nowadays (Smart Meters are said to be among the worst for your health, and wireless DECT phones [they make baby phones w this tech too
], cause the base station is radiating on dangerous freqs *all the time*(unlike a common cell phone) (at least if the phone is off it), like having your own cell phone tower...). The smart phones are worse again too, always polling left and right (unless you deactivate that).
I do realize I may be throwing different interference sources together here maybe (a common mistake in this "field"
)
Most are bad to very bad for your health, but only some may be the cause of the Axe probs.
I may look up a bit about those wires you have if I have more time.
Good to hear yours is fine too in another home.

Until further notice, here are some more opinions from the Top Dog
- Cliff, 3/2014: This means there is a magnetic field being generated by either the Axe-Fx or the monitors or something else that isn't there when using the Boogie. P90s are single-coil pickups and therefore suffer from magnetic interference. Magnetic fields are caused by currents in a loop. The hum you hear from a single-coil pickup is the AC power creating a magnetic field that is generating a voltage in the pickups. Typically you can find the offending source by using your guitar as an antenna and moving it around. The key to minimizing magnetic fields is to minimize the loop area. Ideally the current going into a device should exit the device on "neutral" conductor. If, for some reason, the return current is flowing through the safety ground you may generate a large magnetic field. Return current should never flow in a safety ground except under a fault condition. Some old houses have very poor wiring where the AC line and neutral are not run as pairs. This invariably causes extreme current loops.

- Cliff, 12/2013: It is important to differentiate between "noise" and "interference". Technically noise is thermal noise created by the resistive components in the guitar itself and the electronics in the amplifier (or Axe-Fx). Interference is unwanted signals coupling into the system somehow. You can't do much about noise unless you want to reduce the ambient temperature significantly. The amount of noise produced is 4KTBR where the T is the temperature in Kelvin. Cut the temperature in half and you'll cut the noise in half. Unfortunately both the equipment and the human would probably not function at that temperature. Interference is a two-sided problem. There is the source and the receiver. The source can be fluorescent lights, dimmers, transformers, computers, monitors, etc., etc. The receiver is your guitar. The humbucker pickup was invented to combat the interference at the receiver. Interference in electric guitars is primarily magnetic since pickups are magnetic transducers.. Magnetic fields are generated whenever there is current flowing in a loop. The strength of the field is proportional to the area of the loop so keeping the loop area as small as possible can reduce interference. Removing the source of the noise is recommended in recording environments. There are a variety of approaches that may be beyond the scope of this quick posting. Some are obvious. Others are more esoteric and involve making sure that the loop area of the electrical distribution is as small as possible. One common source of interference is the USB cable. USB is improperly specified and requires a ground at both ends of the cable. This creates a ground loop which can induce noise currents in the interconnected equipment or radiate noise due to current flowing in the shield in a loop. Using a USB cable with an integrated common-mode choke can help. Make sure all your equipment is plugged into the same AC outlet (or power strip).

- What are the biggest culprits of noise in a passive guitars electronics? And are there any modifications that work to lower it?
> Cliff: There are two types of "noise". One is thermal noise, the other is more correctly identified as interference. Thermal noise (Johnson noise) is a function of resistance, temperature and bandwidth. The noise voltage is given by sqrt(4KTBR), where K is Boltzman's constant, T is temperature, B is bandwidth and R is resistance. Thermal noise is "white" and contributes "hiss". There is little you can do to reduce thermal noise. You can use low impedance pickups but then your signal level drops too so the S/N ratio isn't improved. Active pickups can sometimes help if they use a good low-noise preamp. Since noise power is a function of bandwidth you can use a lowpass filter to reduce the noise. Interference is hum, buzz and any other non-stochastic process. Interference is not noise. Noise is random, interference is not. Interference can be mitigated. Shielding the guitar, using noise-cancelling pickups and accessories and other techniques can reduce interference to negligible levels. Sometimes it's easier to kill interference at the source, i.e. get rid of the old CRT monitor.
