If you need just buffer the piezzo signal before you go to your amp or a passive DI, it seems works very well! I don't know to tonal character of this unit, but since is a Mosfet design gear probably adds a little tube like warmth. Also seems a very quality unit at a good price. I also interested to this unit, but never tired.
Here is an exchange of letters:
"Hi,
I just have one question!
How rated the input and output Impedance of the Bajo Mos pedal?
Thank you in anticipation,
Best wishes,
Jozsef,"
"Hello Josef,
Thank you for your email! The input impedance of the Bajo Mos is high, about 10 Meg. The output impedance is low at around 3K. Thanks again! Best Regards,
