This is a good start on one of the ideas that I mentioned. 

When I was about 8 years old, I accidentally plugged the mic from a tape deck 
into the external speaker output. Suddenly there was music coming out of the 
microphone -- but that is impossible!!!! Of course a speaker and a mic are 
almost exactly the same thing electronically. So how can we induce a string 
to vibrate? Maybe we can just use a guitar PU to generate the electromagnetic 
field which induces the string to move. We would first need to build an 
amplifier module which would be capable of driving the PU impedance of 
approx. 10K ohms. This would probably be a trivial module to build and you 
might be able to drive the PU from a standard MOTM module (1K output). I also 
would buy some of those cheapo EMG PUs from Stewart Macdonald's (I think 
they're about $25) and suspend these over the guitar. I wouldn't just plug in 
a 59 Les Paul with original PAF PUs and see if that worked.

Thanks! I'll look into this.
