Octave effect on Green Ringer

Hah. Audacity's Tone Generator tool is pretty useful!

I imagined there would be all sorts of Impedance and Cable Capacitance issues running a Headphone Output into a Breadboard Project, but so far so good.

Do you guys ever just run your PC sound into breadboard projects while working on them?

I can try Audacity. Any tweaks I need to make to the circuit for the Low-Z Source?

I have no idea, but you can always put a 15k or 47k resistor in series with the sound card output to your effect's input to see if it makes any difference.
