Celeste,

The output of the MOTM is an electrical signal, not a mechanical signal. So, it
won't vibrate the string (well, not at the voltages from the MOTM; I'm sure Stooge
Larry has some amazing high voltage wire bending stories ;). What you would want is
the output of a transducer that changes the electrical energy to mechanical energy.
This would cause the wire to vibrate and yes, it is the basic principle of a spring
reverb. A guitar pickup translates mechanical energy (a vibrating string) to
electrical energy.
