Hi, I got an Ibanez sr650 and I'm noticing that I don't get any sound when the EQ is switched off. I don't know much about active basses, but from what I understand the bass is in passive mode with the EQ off? My amp doesn't have any passive or active switches and I also use Pod Farm which to my knowledge doesn't have anything to adjust between the two. I've tried replacing the battery with no luck. Is there something messed up internally or am I just missing something?
