Alot of unwanted noise with the second Tubescreamer.

C-minor

When I have just one Screamer on, there is no noise going through the amp unless I play something.
When I step on the second SCreamer, I get a tremendous amount of noise. Not feedback noise. Just like an airy static noise, if that makes any sense.
Alot of wind air sounding noise.
Is there a solution.
Would a Noise suppressor help this?

a gate of some sort would kill it, yes.
