Please don't blast me for posting here. I have a strange issue and wasn't exactly sure where to post so I just put it here. I practice bass in my downstairs game room and use a old, incandescent bulb, pull chain floor lamp to see. The strange crackling noise happens whenever I reach up and touch the chain with my fingers, with everything plugged in and running. What could be causing this noise? Could it be a grounding issue with the bass, or instrument cable? Some other details: I have a Fender passive bass, Avatar SB126 cab, and a KXB-500 Kustom amp. I don't think it has to do with the outlet, as we just had a dedicated line put in just for my amp. All other electrical items in this room are plugged into other outlets. The noise, however, happens no matter where I plug in my amp. I explained this prob. to the electrician that installed the new plug, but he had never heard of my issue. Also, I called Avatar about it and they said that I may have "dirty" power and should use a Furman power conditioner to solve the problem. I am not sure that this would solve anything as I mentioned that I have this problem regardless of where I plug in the amp. Any ideas about how to get rid of the crackling?
