Seems to me that it wouldn't be that hard to build a little op-amp circuit
to convert any of those signals, to go to S-o-G would just need a little
mixer circuit, and the signals being played with are all far enough apart
in frequency that splitting them apart could probably be done with just a
simple eq circuit.  Don't we have at least one analog guru on this list
somewhere that could come up with a schematic?  That would really help us
low budget scavengers that don't have "mother lode" dumpsters and have to
work with what we find.
