This may be a stupid question. I understand where to hook it up on the back of my amp but where do i hook it up to my recorder. Do i put the line directly into either input A or B? I mean instinctively this seems like what i should do but I'm paranoid about hooking up my 100 watt jcm 900 to it out of fear of blowing it up or something.

Thanks in advance and any peace of mind someone can give me about this situation is greatly appreciated.
