Hi Gianni,
I use this "quick and dirty" piezo preamp designed by Francis Deck between =
my pickup and my LS-11 mic input. It's a simple and inexpensive build if y=
ou can find one of his recommended JFETs. The preamp provides a few dB of g=
ain, and more importantly restores the low frequency response.

Francis sells a version of this with a few bells and whistles (like a gain =
knob and a low cut filter) but they are not available outside the US and Ca=
nada. The DIY version linked above works very well in my experience.
Other similar circuits can be found by searching the web for "mint-box piez=
o buffer" like this one:

I can only speak for the F. Deck version, but others give you options for t=
he JFET and the associated resistor values.
best regards,
