Hi, I was wondering if anyone could help me. I have recently acquired my dads old Levinson Blade B3 or B4, its hard to tell which but I am fairly sure its a B3. I have no use for it as I am not a musician so I would like to sell it. However, the problem is it does not work. It has active pickups and unfortunately the guitar was left alone for a long time and the battery connection corroded and fell off. I am trying to understand where the battery would connect to so I can buy a new connection. Does anyone know the internal workings of one of these things so I can try to fix it? I can post pictures of the circuit board if anyone is interested. Aside from the corroded battery connection, it has been kept in good condition and as I understand, its a good bass. Any help is greatly appreciated.
