i have a Boss RC3 looper as part of a four pedal board which I play into a Vox AC15C1. At home I record loops to practice with and then off I go to band practice on Wednesdays. The problem is that everything works fine at home at low volumes. But when I get to practice and crank up the volume it doesn’t seem to work. Basically I use the looper as a drum box and at loud volumes either the dr7ms “disappear” or more often the guitar breaks up and disappears. I have heard people say that a vox doesn’t take pedals well. Is this the issue? Or is my cheap power supply the problem? Or is it something else? Has anyone else had a similar issue?
