The nature of piezos is that they have extremley high impedance, whereas 
mics have a low impedance. If your preamp doesn't match the impedance, 
you get less signal which means more noise. Piezos need their preamp 
close to the pickup, because they also pickup electromagnetical noise 
more likely.
But if you can feed the pickup signal into your head phones clean, just 
use the identical input as preamp...
You could even use the headphone output and feed it into your 
ultralight, just turn down the volume...
