I recently got a brand new computer. Everything was fine until I plugged my electric guitar into my amp. When I switch on my guitar amp (guitar speaker) I can hear a weird noise. It sounds like the noise that that goes through your speakers when you put your mobile phone next to it.
There is nothing wrong with my guitar or guitar amp and I didn't have any similar problems with my old computer. Can anyone help me?
Its probably EMI (Electromagnetic Interference). This happens with cell phones and anything else that puts out a signal. In your case, its your guitar amp which is probably leaking electricity or other signals, which get picked up on your speakers.
TheLQ is correct, but to be more specific in your case the amp is "receiving" a rouge signal from somewhere. If your amp is not connected to your computer in any fashion then I would first make sure the outlets you are using are properly grounded (three holes instead of two). Do not use one of those little gray adapters for your computer or your amp. If the outlet(s) you are using are properly grounded then the most likely source of the sound is from a wireless device somewhere. It could be a cell phone, a cordless phone, a bluetooth adapter, a wireless router, etc. Start unplugging wireless devices one by one until you locate the source, then remedy as you see fit.
