Piezos have a capacitive impedance, together with the

input impedance this forms a first order highpass filter. A typical mic

in the high audio range, with 6 dB/oct below that. Could be EQ'd in theory,
but for musical use it's usually better to use a high-Z preamp.
Have you tested Guitarix? Hermann claims that Guitarix fix such an
issue, if you know how to handle Guitarix. I'm to bonehead to waste my
time trying to fix such a technical issue using Guitarix, perhaps
somebody approachable is willing to learn how to use Guitarix to
eliminate technical facts by the magic of Guitarix tube amp emulation
algorithms.
