There's to much interaction regarding the dynamic playing done by the
guitar player and the preamplification, unlikely that it make sense
trying to fix it by a digital algorithm. The output of most simulations
usually is without dynamic and add much noise.

And in theory it could, Piezos have a capacitive impedance, together with

input impedance this forms a first order highpass filter. A typical mic
input is around 2 kOhms, this would place the cutoff frequency somewhere
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. but I don't think Hermann is advising anyone
to use Guitarix to fix a technical issue such as this one. For a piezo
pickup you need the right preamp, either a very high-Z one or a charge
amplifier. Not to create any 'sound' but just to make it work as intended.
This has nothing at all to do with Guitarix or even tube emulation in
general, so you better stop whining about it.
Actually I was talking about preamps when using a guitar plugged into a
mixer. Feel free to search the mailing list archive. Hermann recommended
to use Guitarix and started dissing me, when I said that Guitarix can
not provide what has to be done by the right amplification in the first
place. Please don't misrepresent it. Hermann claimed something without
understanding what the discussion was about and he claimed something
that should be provided by Guitarix, that can not be provided. I pointed
out that even plugging in a Boss transistor stompbox between guitar and
mixer (or sound card) sometimes is better to fix the main issue, than
using amp and speaker emulations. Hermann claimed that this isn't true,
Guitarix does the trick, no correct preamp is needed.
