So I figured out that it was my compressor causing my rig to make a loud popping noise. At last practice I disconnected my rig and just plugged directly into my head and cab. It sounded way better too for some reason. I like that ampeg grind. Now the thing is. Could it just be my effects loop? Or the actual compressor. Is there any way of figureing that out? Or could it also be that i share the compressor with my guitarist?
