Has anyone else had this problem? I'm working on a new board, which is home to a Lovepedal Believe and a Mayer Octavia TC. When I engage the Believe, my amp starts blaring a Journey song from a radio station. The Octavia does it as well, but the amount of interference is linked to the drive knob. With the Believe it is full-bore radio, louder than the guitar signal. I've used several other octave boxes on other boards and never had this happen. Any ideas?
