I did the same experiment for the southport CD although that leaned more towards sounds from a fan, but had one track in there with just handling the jackAll sounds come from the ground loops/hums created by handling one end of a guitar cable which was feeding through about 8 or 9 guitar effects pedals, and into a Line6 GuitarPort.
The pedals surely bring this a different taste and make it sound grand in my ears.
Cool to be hearing you again though, I can imagine that the rut you were in was getting to choke a bit. This is a good break out track
Can we see a continual on the minute series too
