My peavey fury 4 is active, has weird stock soapbar pups, and a 3 band eq. It has been crapping out alot lately. I had to get a new volume pot. After I got my bass back everything sounded surprisingly good. But then the next day I noticed a dramatic drop in volume and when I pulled the string hard, it would give a violent cutting sound. Also, the eq did not work at all. I now have to turn up my amp to 10 on everything including each band of eq for band practice. I thought I needed a new battery for it so i put one in. I tested the old battery and it was dead. The new battery I put in was full of life. After putting the battery in, I still have little volume coming from my amp, and my eq is still not doing anything at all, but, I no longer have that violent cutting sound when I pull the string hard. I took the battery out of the bass just for the heck of it. When I did this, nothing was changed. My volume didnt drop, my eq didnt work. I don't know what to do.
