I have a Fender Hot Rod Deluxe Reissue. I've had it for about 2 years now. Its a decent amp, never had any problems with it. Today out of the blue, with I run any sort of distortion through it, whether its the distortion channel on the amp itself or the Boss Metal Zone MT-2, I get lots of buzzing. On the clean channel or with the box off, it sound perfectly fine and I can go as loud as I want with no problems, but the second any sort of distortion is turned on, no matter how much distortion or how loud it is, I get buzzing. Any ideas on what could be causing this?

I have a Ibanez SA260FM, stock except for the Seymour Duncan humbucker (Parallel Axis Trembucker Blues Sarasceno PATB-3) I put it and I use all Mogami cables, if it makes a difference.
it could be one of your tubes playing up, there's something where a tube will ring of it's own accord, especailly when it is realy pushed, i can't think of the term but someone will probably say what it is
are the tubes 2 years old?
