My tonebone pedal has picked up radio stations from time to time....hadn't happened in a while, but it keeps happening where my band is practicing nowadays, and it is pretty annoying, so I have been using my Crunchbox instead. What causes the tonebone to pick up radio stations? My Crunchbox doesn't pick up anything, and neither does our other guitarists's Marshall Jackhammer. I am playing through a Fender Twin and a PRS FYI. Luckily, the radio station thing has never happend at a gig! Help?
