Hey guys, I need help determining what capacitor I need. I recently wired a good buddy’s acoustic with two piezo’s in series stuck on the soundboard close to under the bridge running to an end pin jack. It sounds great, but the highs are a little much. I was hoping a putting a capacitor in there would help it out some. My problem is that I don’t know what value to use. What would filter out a lot of the highs and maybe some mids?
