Who knows about the details of the P22 electronics and can educate me?
As far as I know the Piezo goes into an active preamp (thats what the battery is for, right?) and so the output signal should be low impedance or "active".
But then how is the mixing with the passive/magnetic pickups of the guitar done? Does their signal go through the active preamp, too, and is turned into low-impedance? Does the preamp influence the sound of the magnetic pickups and do they still work if the battery is dead?
