Hi - recently installed a couple piezo pickups in my cajon (box drum). The very high signal level was clipping my audio interface, and i learned online that you can wire capacitors in parallel with the element as a means of reducing the output level.
I used a non-polarized 0.1 uF up and it works fine. If I used a polarized capacitor, will it also work? If so, does the orientation of the cap matter? My loose understanding is that capacitors pass AC and block DC, which would seem to imply that polarization/orientation isn't relevant, but my grasp on this stuff is tenuous.
Also, my understanding (and my listening tests seemed to confirm this) is that such an arrangement has "no" effect on the frequency response (within the general parameters likely to be in play, here.) Sound right?
Thanks for any ideas!
