Hi all - I have a strange issue going on with my Stomp. Whenever I have it plugged into the computer with the USB cord I get loud buzzing. Even more weird, the tone of the buzz will alter as I close or open programs or web pages. This is most problematic when editing or creating presets. I made sure the Stomp is not assigned to be my audio interface for the computer. I'm running Windows 10 on a Dell laptop that is a little older now.
