In simulation with a 1 megohm load... no. The bigger the shunt cap
(more attenuation) the better the low frequency response.

If you want to roll off the highs, you need some series resistance
between them....

I was thinking of a system where I was driving the piezo, not using
it as a generator...  ;^)
