    I am using a 9 volt wall wort to power 3 guitar effects pedals. What I would like to do is clean up the dc voltage as simply as possible. Theres a faint hum in the pedals and I assum its because of the wall wort not being a fully regulated dc power supply. How can I help clean up the dc voltage as simply as possible?

    Hang a 500uF cap across the output of the wallwart. Make sure you observe polarity.

    There is a small cap 25v 470uF I have some much larger caps 200v 470uF / 200v 330uF / and a couple Big caps at 200v 820uF Would any of these be a better choice and which one?
