I just bought the Ultra II and can't get the mono output to work unless I remove the battery. I'm only running with one cable hooked up, so when I go from the stereo/namomag output jack with the battery in, the namomog works. Pull the cable out and move it to mono, I have no output. Is this a problem or am I missing something? There are no instructions on using this, and I'm very disappointed. If I run two separate cables out, one to my amp and one to my toneport, the mono output still doesn' work. Remove the battery and the mono output works like a regular electric guitar. WTF?
