Hey guys I recently got back into playing and picked up an active bass. I noticed today (not sure if this was the case before) that when I set the double stacked bass/treble nob flat (middle notch, no?) then I suddenly get no sound whatsoever from my amp. If I move either nob out of the notch even slightly, boosting or cutting, everything is fine and sound comes out normally. Is there an issue with the bass? Is this normal? Should I try something else? Thanks. Sorry if this is the wrong forum. I wasn't sure where to post.
