If you're a guitar player you've likely experienced this before, but ever since I moved into this new house I've been getting fm radio playing through my guitar amps. If varies depending on what guitar/amp combination I'm using. My vintage 78 JMP has been rendered useless, my orange amp has (until today) been fine. The radio interference is worse when playing with active pickups, and sometimes disappears with passive pickups.
Today I noticed something strange. I was playing a guitar with active EMG p/u's, into my Orange OR15, which usually is very quiet and free of any RFI. But, then the radio came blasting through, loud as hell. The only thing different this time was that I had a wah pedal plugged in, but not engaged. I found that if I disconnected the 9v wall wart power supply of my wah pedal that the RFI went away completely.
So my question to everyone is: Am I getting radio interference through my A/C power outlets? Or is it a combination of different factors creating a perfect storm of fm radio hell?
Any suggestions or tips for eliminating this?

Tried different cables?

Yes, and with higher quality cables I eliminated a little bit of noise, but the Radio Station was still blaring. I tried plugging the wah pedal into a different power outlet and it helped alot. The RFI is about 50% of what it was. Still kind of weird that it only happens with thw wah plugged in.

Somebody tell me if I'm wrong - I certainly could be...but could one of the tubes be the culprit?

Happens to me sometimes with my DR clone, but only with certain settings (preamp gain on zero, unbelievably...), otherwise it's inaudible, so it's not so bad. I think I can sometimes hear the Paris taxi drivers talking too. I actually based a whole ambient soundscape backing track around it, sounded great.

Tubes, no. Wah and fuzz, yes. They are notorious antennas. Power them with regular carbon batteries, you’ll get better sound.

Lots of good advice in that thread. AnalogMike is the man!

Thanks guys, I just check out that threat on TGP, some good info there. I'm going to have to do some serious troubleshooting, but first lets hope powering the wah with a battery will help.
