I just went down and tried mine. Yeah it has about the same amount of "rush" noise as your video. Plugging in an axe changed the sound a little bit. Funny thing is I never noticed this before, I would have said the thing was quiet. I just never get the volume settings up that high.
And yeah it gets hot. I had it repaired once and the thing had melted parts of the board.
I like this amp. The clean channel is great but I can't get anything but mud of the lead channel, must be bugged up. Dosen't matter to me I have not switched a channel on an amp in years.
