I have a Vox AC15c1 and the pedalboard below. Granted, there are extra distortions on there but I am just trying them out and will pick my favorite soon. Anyway, at home I am getting major feeback sounds and noise when the board runs through my Vox and my guitars are plugged in. It's minor usually but when I hit a pedal such as the Pinnacle or the SLO it really ramps up the feedback and noise. You can't even use them. Now when I pull one of those pedals off and use the pedal by itself as a standalone pedal I don't have a problem. The pedalboard is laid out bottom row right to left > right to left also on top row. (Keep in mind I'm a pretty new player and new to pedals etc.) Does any of this make any sense?
