These kind of discrete transistor circuits are kinda mysterious for a beginner, so this analysis is really helpful

Generally: Overdrive: Soft clipping normally by using diodes in a feedback loop to soften the knee. Distortion, hard clipping, diodes after massive gain increase. Fuzz: internal transistor saturation created by driving one transistor into others.

I loved the video. I wish I lived closer to your university to take your class. You're an engaging teacher.

A very good tutorial. Would it be possible to do an installment on the problems faced when a Cry-Baby is employed before the fuzz-face and an analysis or improvement on the FoxRox wah-buffer (or as I think of it the FoxRox single-opamp-fullrange-booster that allows to recover the signal-losses caused by a 22k or higher series resistance which is needed/employed to raise the impedance right before the input of the fuzz to make it work)? That would be golden! 😊

I am absolutely fascinated by this series and your explanations on these topics regarding audio applications in electronics. I’m currently finishing my 3rd year studying electrical engineering in college and I’m developing a strong interest in audio electronics. I have been watching your series as a supplement for absence of any audio related classes at my college since there are very few signal processing classes here, let alone classes on audio circuitry. I’m even designing my own guitar effect pedals from scratch and getting them fabricated on custom PCBs in the lab. I even have my own synthesizer design in the works inspired by your previous series on analog music synthesis as my senior project. I deeply appreciate the work you do and I look forward to each upload you make. Keep up the good work!

Damn, now you're getting me interested in this study I like anything related to guitars or drums, so making and maintaining such creations would be great

I had one of those original Fuzz Face pedals around 1970. I don't remember why I got rid of it.

I have started building my own clones of alot of vintage analog circuits and am happy to have found your channel, so i can gain a better understanding of how this all works. I would like to eventually get t a point where i understand how changing values of different components will change the tone. Thank you for the information. : )

Shunt-Series-Feedback-Pair..... Remember your Sedra-Smith book from Undergrad :) ??

This fuzz video puts things into perspective! I am planning to build one and this is very helpful. Any plans to go over Octave Fuzz in the future?

13:14 The capacitor at the input may be to shunt unwanted RF pickup.

For a good history, search for Loud 'n' Dirty. There are several parts and the guy needs to be encouraged to continue the series. It's really informative.

Kinda curious how that biasing and feedback scheme can be exploited in other electronics realms. Might play around in LTSpice later and see if I can make anything using it at RF frequencies.

Personally, i would maybe define diode hardclippers as distortion, diode softclippers as overdrive and clipping transistors and opamps as fuzz

Ive been more of a Paul person, but I will also tend to go back and rewatch some of the ones I have more interest in. Can we call that a Pete (Best)?

Excellent analysis. Wish you were around 35 years ago! Lol.

Who was the first person to ever think of this madness???? Where they a god

Please do an analysis of the Pro-co Rat. It's a bit of a strange one, hard-clipping distortion with filtering stuff in the feedback and a unique tone stack. And was designed about 20 minutes from where I'm posting this.

@@Lantertronics I have and I did and I do too :) The filtering on the op-amp feedback is odd and the whole thing isn't like anything else I've seen. The analysis on the site doesn't address the filtering stuff and the tone stack and why it's still a bit of a weird beast in the world of distortion. Looking at their analysis they ignore C5 and C6.

Is there a harmonic difference when using pnp vs npn transistors?

@justovision

2 жыл бұрын

Nope. You just swap negative and positive. Germanium transistors were more common in PNP and the fuzz face just ran on batteries so it didn't matter. You could make a PNP version with silicon the same way.

I’m not even in your school just curious. Thank you.

Hello! I’m a beginner when it comes to pedals and electronics but I’m eager to learn. Can you simply explain why fuzz sounds generally horrible with a bass guitar?

@Lantertronics

Think about a choir arrangement -- base and tenor parts are generally spread out compared to what you can do with an alto and soprano part working together. Similarly, a string quartet will have two violins and a viola and bass, and not say on violin and a viola and two basses. When you play a note with a fundamental of 100 Hz, you get the harmonics at 200 Hz, 300 Hz, 400 Hz, etc. But we perceive pitch on a logarithmic scale, so while the octave above 100 Hz is 200 Hz, the octave above that is 400 Hz, and above that is 800 Hz, etc. So harmonic content at a lower end of human hearing is going to sound denser than harmonic content at the upper end of human hearing. A fuzz will add harmonics in a way that's going to be perceived as denser and more cluttered at low frequencies.
