Im wondering if anybody can help, Somtimes when i switch off my amp, windows makes a sound telling me that a USB device has been disconnected. Of course, i haven't removed anything. The PC and the amp are on the same Power adapter, and are on opposite sides of room. Does anybody have any ideas why the hell its doing this?

Thanks again.

No idea. Maybe some kind of radio waves or something? whenever my cell phone rings or vibrates near my amp, it crackles and cuts out a bit.
That's very odd.

You have entered the Twilight Zone
Beyond this world strange things are known
Use this key, unlock the door
See what your fate might have in store
Come explore your dreams' creation
Enter this world of imagination
Is the amp connected to the computer? I know the peavey vyper has a USB thing, maybe other amps do to.

If not, that is very strange!
