Hey Far-seeker,
Almost a year later (correct me if I'm wrong, but I figured it would be better to revive this thread of mine rather then start a new one and have to back-reference to this one) I finally got around to working with stuff again. The issue I was having with the DC blocking out the sound was that I need decoupling capacitors on the ground side too; but I got it to work!
So it would be like the attached schematic: Guitar Power Over Audio.jpg (it's ugly, I know).
Question:
Would I need to get caps rated for at least 9v in this case, or would it not matter as it's being used only to block power, not absorb it?
Still a little confused on the Arduino and power supply side; would/should I use an inductor or diodes to filter out the AC signal, or will it not matter?
Don't want to damage the Arduino, and I may need to filter the 9v anyway otherwise it could bleed into the circuitry that will be processing the guitar's signal.
Thanks,
Matt
