I've had good luck taking pedals to Catholic priests to purge out the voices. By the way, some of them actually really love pedals (insert pedaphile joke here). 12 years of Catholic school, so I can say that (but never any... issues).
Seriously, I remember having electronic guitar equipment pick up radio signals way back when. I think my Vox treble booster was the worst. I assume it had to do with lack of shielding?
