I recently picked one of these up, and while trying to get it working again have noticed that some of the wires aren't connected to anything. I'm now trying to rewire everything back together and replace some of the worn out pots... But I have no clue as to how the thing is really supposed to be wired. I have contacted Hohner and gotten diagrams off the internet but they are all for a B2A bass that had an active circuit with 11 wires leading off of it and had a total of 3 pot one of which was a dual concentric... the bass I have only has 3 single pots... So has anyone ever run across an older Hohner with a layout as I describe? If so could you offer any assistance on where the wires are supposed to go... I swear the insides look like someone threw up solder everywhere to the point that it is hard to tell where some wires are actually soldered.
