The only other building I've found that it does this is at my friend's house, and there it is much more subtle. Everywhere else I play (and I'm using the same Acoustic B100 amp everywhere I go) I don't even get the faintest interference on my bass. The buzz changes whenever I move around my bass so I'm pretty sure it's interference from something around me. Also the buzz gets drastically worse when I move the pickup blend away from the center. If I try doing any other blend of the pickups the buzz becomes even louder than my playing. I've tried turning off my wireless router and even lights but still haven't figured out what's causing it. Any ideas on how to fix this would be greatly appreciated.
Yeah, the way you get rid of it is get rid of the single coil pickups!
What you've got is pretty clearly single coil hum. I comes from things putting out strong magnetic fields (like large power transformers). The only cure is to use hum canceliing pickups or to stay away from the hum field (my old amp used to be really good at creating single coil hum, and some lighting systems do it really well too) or to keep both pickups on at the same volume (which coverts them to hum cancelling).
It's just one of the facts of life that if you love single coil tone, you have to deal with single coil hum. You may be able to find the source and turn it off by just moving around the room looking for the loudest position. Also if the bass has any normal hum (which goes away when you touch string or ground) that will contribute to the single coil hum. In that case shielding will tend to make the over all effect much better as without the normal hum the remaining single coil hum won't sound so objectionable.
But really, if you want single coil tone, single coil hum is pretty much a fact of life.
