I have a 80's Charvel Hockey Stick P/J bass. When I played it my amp sounded like the speaker was blown. I tried a new amp and the same thing happened. It dosen't happen all the time it comes and goes that's why I think it must have something to do with the bass. Maybe the electronics. Can someone please help I don't know what to do and can't get in touch with my usual Bass guy don't know where he went. Thanks
