Is this a good noise? well surely not.

My amp, while just sitting thee, no guitar plugged in, not even a lead (tried it without) randomly gets the noise you'd get if you put a microphone out in the wind.. and then sometimes it'l pop and then go away.

I dunno what this could be?
Its not very old..

Any idea?

dude i heard of that before......when you turn it on turn your gain down but not off and tell me if it still does it?
Change your preamp tubes and clean the input jack. Clean the pots if they're real old.
