so I am new to the Kemper , and I feel dumb for asking this , but here it goes. all my guitars with passive pickups sound fine, but whenever I plug in my brand new ec1000 with active fishman pickups, it doesn't make a sound, the tuner doesn't even pick up anything. put brand new battery in back and it plays through some amp sims I have. I'm wondering why the Kemper picks up my passive guitars but not my active ones? any assistance would be appreciated thank you
