This isn't that big of a problem, it actually kindof sounds pretty cool, but I want to know what's causing it. Sometimes, when I'm recording high gain stuff and changing chords, I get this sound that almost sounds like a phaser. I noticed it on my POD pro back then and I'm starting to notice it on my RM preamp on the ultra channel. Could it be some sort of phase problem, or could it just be too much gain? If you want to hear what I'm talking about, take the link in my sig. and listen to "Rock Out." I think you can hear it a little in the chorus. That was done with the RM preamp. I don't have the other recording where it was very noticable that was done with the POD. Like I said, it's no big deal, but I would like to know what's causing it, and how to get rid of it. Thanks for any help.
