I'm getting a loud popping noise when engaging the two true bypass pedals on my board - Analog Man King of Tone and a MXR Phase 90. Any ideas why? The board is powered by a Voodoo Lab Pedal Power 2 and is connected with George L's and Mogami Cables. The Pedal Power is plugged into a Furman power conditioner when on stage. Is this just the nature of the beast? It does this in my house, at rehearsal and in all the rooms we play in so it's has nothing to do with the location that I can tell.
