Debugging Basics for Pedals and Effects

In this video I walk through basic debugging from start finish. We discuss the necessary tools and materials, list the techniques for most efficiently finding problems, and then go through a real time debug session for two of the most common problems: no sound at all, and getting sound but not what it's supposed to be. 00:00 - Intro 01:06 - Tools and Materials 09:37 - No Signal Debugging: Power 15:15 - No Signal Debugging: Audio Probe 22:19 - Signal Not As Intended Debugging If you are interested in the circuit test box I used in this video, you can read more at https://scientificguitarist.wixsite.com/home/circuit-test-box For more info on opamp gain stages, here are two great articles: https://www.electronics-tutorials.ws/opamp/opamp_2.html https://www.electronics-tutorials.ws/opamp/opamp_3.html Links to combination oscilloscope/logic analyzer/multimeter/power supply devices mentioned in the video: https://espotek.com/labrador/ https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm2000.html#eb-discussions https://digilent.com/shop/analog-discovery-2-100ms-s-usb-oscilloscope-logic-analyzer-and-variable-power-supply/
