Debugging the Pandemic Pedal #96 using an Audio Probe and Digital Multimeter

I had put together a tutorial on designing a test box for my builds. You can see it here: https://www.pachydermpedals.com/tutor...

Some people asked if I could make a video showing how to use it. Well this is the video I recorded. I have been trying to edit it into a tutorial but its not. This is me using it and a digital multimeter to figure out why my Madbean Pedals Snarkdoodle was not working. In the end I solved the problem. I hope you enjoy.

If you have any suggestions on what else you would like to know about let me know. You can learn right along with me.
