Hi Guys, I have a problem. I have been having some problems recently with my setup. It seems to be making an annoying buzzing sound whenever i use it. I have tried different settings, and checked that everything is earthed properly on my guitar, but i cant get rid of it. Before you say it, I know its not normal buzz you get when playing loud on distortion or w/e.

My Setup is:

Roland Cube 30-----Jackson JS30DK Dinky

Thanks very much for any help you can offer.
