Hissing when touching the strings

[Gearhead]

Only today I noticed a problem I haven't had before. As soon as I pluck a string there is a hissing. It's not the guitar I tried different ones all with the same result. It doesn't happen with acoustic guitars. It's not the cable, it comes from the Axe - since I have the same results with headphones.
I'm on 6.02.

Any ideas?

Thx guys

The gate is turning off.

Are you playing live? It might be the audience.

Probably what Cliff said though.

Thanks, Cliff.
