This question already has an answer here:
i have an electric guitar (Fender Stratocaster classic series 50's mexican) and a Fender Champion 40 amp. Everytime i put my amp on and turn up the volume it makes a really buzzy sound. I figuered out that this happens when im close to my laptop witch i usually play! Any good solutions except from change my laptop ( also it hasnt got any battery if that makes any sense, its always plugged in)! Thank you!!
