Bride Of Synthog has a plastic wiring bridge

The bridge contains 13 mini-boards with 3 solder pads on each.  3 lengths of solid bell wire connect these pads to the 3 voices on each IC.  There are six holes drilled next to each mini-board, through which wires running to the keyboards will be routed.  The wires will be soldered to the pads, but they'll pass through the holes first.  The holes will act as a strain relief.
At one end of the bridge, wiring for the power input, keyboard output, and audio output are routed through the plastic.  Connections to these wires will be made with wire nuts.
