So I was tweaking the volume on the push/pull knob on my 44-01, and then I pull for passive, and the entire knob comes out! I can put it back in and the volume works fine, but no longer can I do passive, it's now permanently on active. Here are some pics: I can put the knob back in, and it looks normal Here's how it looks when I try to do passive and it comes out This is the first time I've ever experienced a problem with my bass. Can anyone tell me what I should do? I have no experience with issues like this, and am totally lost Any help is greatly appreciated.
