Title: Hearing neiboors radio through my rig
Post by: slapbass on March 17, 2005, 11:07:05 AM: I was getting ready to tear the battle worn Epic apart but had to play one last time. Well I turned around to look out the window and then I heard voices. turned back again to see what was behind me. Nothing. Anyway after felling like I needed to go to UVA hospital and get admitted. I turned and heard Kool and the Gang being played. So when I face my neighbors house and they have the radio on I am picking it up through this bass some how. So I plugged in the old Series 1 and nothing happed I also tried the Stanly Clark. Has anybody had anything like this happen?

Thanks,
Dale

I was getting KC101 everytime I faced the guitar in that general direction... It was happening w/ his Telecasters too. I just pray Im never doing a gig (like at a state fair) where there's a DJ booth broadcasting live.

Around 200 yards from people's houses was a BBC World Service transmitter station, and people's TOASTERS started to produce Russian radio! What happens is when you have 2 metal plates and a wire, they act like a capacitor. I can understand how a pickup might be affected, but a toaster with built-in radio, now that's new!!

Does the bass have the ferrite bead in the cavity?
Is the cavity properly shielded?
