Tone Stack Design Master Class 1 - Rat, Big Muff, Ampeg, Fender, Marshal Vox

Описание: This video provides a comprehensive study of passive tone circuits used in popular guitar pedals such as the Rat and big Muff, and amplifiers such as Ampeg, Fender, Marshal and Vox. It focuses on understanding, designing, and analyzing several fundamental passive filter topologies by breaking down their components, behavior, and frequency responses through practical examples, mathematical equations, and simulation tools.

00:00 Introduction - Types of filters: RC, Tilt, Shelf & FMV
02:16 Reactance and voltage divider networks
04:57 Tools: Spreadsheets, Programming, LTSpice, Tone Stack Calculator.
06:12 Rat Pedal, RC tone stack analysis
11:47 Modeling the filter in MatLab
13:34 Impulse response analysis
15:20 Big Muff and DS-1, Tilt tone stack analysis
18:49 Tilt demonstration using an Impulse
19:38 Shelf Eq or Baxendall /James analysis
20:56 High frequency shelf analysis
24:50 Comparing proto impulse response measurements to LTSpice & Tone Stack Calculator simulations
27:15: Fender, Marshall, Vox (FMV) tone stack analysis
29:28 Modeling in Python and the Tone Stack Calculator
31:40 Bonus: Bandpass
33:49 Conclusion

Note: for the divider networks, using impedance is more exact than treating the reactance as a resistance. For more info:    • Understanding Phase Lag when analyzing aud...
