I agree with PRR about the unsuitability of a transformer. (The trouble is, the impedance the piezo wants to see is far higher than you can get out of any reasonable transformer.)
Try connecting the piezo straight to the amp input. If that produces thin or missing bass, try wiring a small capacitor in parallel with the piezo. That may seem like madness, but it actually works very well because of the nature of the piezo (itself a capacitive source).
By "small capacitor", I mean anything from 0.01uF to 0.1 uF or so. The bigger the cap, the smaller the voltage arriving at the amp input, so don't use a capacitor bigger than necessary to bring up the bass.
If you know the input impedance of the amp in question, I can give you a better estimate of the proper cap value to try.
