I'm going to be building a long string instrument, using metal strings. 

I can pick up the sound ok either using a guitar pickup or a sound board with piezo, but I'd also like to feed the sound _back into the string using some kind of transducer (kind of like a gigantic spring reverb, I guess).

Can anyone point me towards a bit of hardware that would do that? Something I can drive with a small amplifier. It's going to have to be fairly robust, as the strings will have quite a lot of tension, so I don't think soldering to a piezo will do the trick (though I suppose I could mount a piezo to a small piece of sheet aluminium and attach one end of the string to that). So I'm assuming either a coil or some kind of linear transducer.
