Data sniffer eurorack set
A data sniffer eurorack set up with an amplifier and a fairly big coil
can be used to get control of the ground sounds.
This coil is sensitive enough to be used with your fingers and
can be used to take data from laptops, telephones,
or any other electronic magnetic fields.
This particular coil is from the 1950s and is big, heavy,
and raw. A mono jack cable is included.
