Check put the vid...(is this "motorboating")

Im about to recap this thing to get rid of the fizz..

But this rumble at starting at model 6 is redonkulous

I was thinkin bad tubes because it does it on lower gain when you put an od or distortion in front of it too..

Never heard this on my MP1 even before i recapped it!

Any place to look would be greatly appreciated!

Does it with noisegate out and in...  Over powers gate on higher settings

Seem to get worse longer mp-2 is on

It seems like a 60 cycle hum...  But..  Dam

Sounds like motorboating, there's a post elsewhere here about it IIRC and had a link to a wiki article on motorboating (

Welcome to the boating club . . . . I re-did the caps as well as R913 in mine and it helped clean that up.
