Half the volume. All settings are set correctly. I am playing up against a hammond b3 with 2 leslies. I have to keep my shortboard unplugged. Thats not cool because i do change parameters a lot. What else could be the issue

It very clear to me that when i have my shortboard hooked up to my amp i dont have the full power of my amp. Ive set it up but it doesnt make no difference. Seems i have half the amp power whn the shortboard is plugged in. Why and how can this be? Doesnt make sense.
