I have a Fender Blues Jr. amp.
Lately whenever i turn it on, it makes this extremely loud noise.
It even does this if the volume is all the way down and nothing is plugged in.

Does anyone have any clue what might be wrong with it/how to fix it?

Your amp asplode.

just kidding
I'd check with Gear Building and Customizing. They know alot about this stuff.
But, maybe bad tubes.
Does it run normally after the noise?
