I don't have any idea how well the digital circuitry is shielded in music and 
audio gear, especially since much of it has a plastic case.  I know that my 
computer puts out an alarming amount of radio 'hash', and it's got a solid 
metal case.
As for shielding on the guitar stuff,  you can shield all you want, but when 
you have a RADIO RECEIVER onto the input of your amp, you are going to pick 
up whatever noise is in that radio band.  Since a lot of industrial and 
electronically generated RF noise is broadband, it's a simple fact that you 
ARE going to pick up noise.  You just have to decide "is quietness and sound 
quality more important than being able to walk around?"
