Designing Dirt Pedals - Understanding Op-amp Distortion and Overdrive

Klon, Rat, Distortion Plus, Tube Screamer are all overdrive or distortion pedals for the guitar signal. Overdrive and distortion are both forms of clipping, which is the process of flattening an audio waveform's peaks and troughs when a signal is pushed beyond a circuit's maximum capability (headroom). The key difference between overdrive and distortion is the type and intensity of clipping and the resulting harmonic content. In this video, we look at gain, soft, and hard clipping, and study each method's harmonic response. 00:00 Introduction 00:15 What is Distortion? 01:10 Time and Frequency Analysis 03:39 What is a Square Wave? 05:10 Timbre, guitar harmonics 06:02 Test Pedal, Modified Micro Amp 08:50 Schematic and the basics of gain and clipping 12:33 Visualizing clipping on the scope 13:37 Soft clipping and harmonic analysis 17:22 Hard clipping and harmonic analysis 18:38 Tube harmonics analysis 19:51 Asymmetrical harmonic analysis 21:38 Conclusion Contact https://calsonics.us/ ECE4448: Guitar Amplification & Effects    • ECE4448 L43: Diode-Based Overdrive and Dis...
