Everyone should own a multimeter with alligator clips on the ends of the leads. Makes life so much easier
I've always thought that the Fuzz Factory is essentially a Fuzz Face where every possible bias point is adjustable, which means you can get just about any sound imaginable (and many you can't). But it isn't easy to figure out or control. The Silktone is a pretty ingenious design. Thanks for a cool and helpful vid!
AION makes a PCB to build a modified fuzz face with EIGHT knobs; that’s a wild one
Funny enough, the fuzz factory circuit has only one control that affects bias directly, the stab control, and it only does so much as limit the input voltage. The real deal is that it uses a negative ground PNP design, already prone to oscillation, and makes it oscillate even more with an input booster and some unusual component values in the negative feedback.
It started off that way but he added a 3rd transistor to the circuit.
Very nice video man. Good informations. I am just dealing with these fuzz problems. Very cool video.
Buying a fuzz face for more than $100 is ridiculous. There's only 11 components in the original design.
You aren’t wrong for pointing this out, but what you should be paying extra for is the amount of time spent on the proper component selection and quality of the few parts used, unfortunately that is not always the case and the higher price is for flashy packaging, celebrity endorsements, and massive marketing campaigns!😂
Great info thanks! I have a circa 2018 NKT/RCA Analogman Sun Face that I just love..
The Barber fuzz pedal is the bomb. Adjustable to no end. Good when you go from Strat to LP.
My Voodoo power supply has outputs that can supply less than 9volts to your fuzz ( or whatever). I’ve gotten results that sound a lot like these low bias settings.
Good stuff man. I built a Tone Bender Mk1 this summer but couldn’t find the vintage correct transistors, so I ended up using some old Russian MP40A’s and it must be affecting the bias because it has a kind of gate effect where it chokes down on anything not strummed really hard. Not sure if it’s a bias thing or if I just need to to keep searching for the right NOS transistors. Thanks for taking the time to share this info. Big Stringjoy fan here and I’m in Nashville too. Feels good to play local. 👍
Try adding a 1M (or thereabouts) resistor on q1’s base to collector to bias it. These russians dont have much leakage so probably need a bit of encouragement to turn on.
What's your favorite classic fuzz pedal?
I have a FUZZLORD VOID MASTER and inside the pedal is a bias, and fuzz trim pots. I tried to adjust them a little and now I want it back to "factory settings". can you help me?
My LPD Soliel has a bias control on the front. The sweep is wide and gets a tone from loose and dirty, to tight and fizzy. I prefer a tighter fuzz tone personally
Thanks! Next time, the effects of different transistors in a wah? 😄
That's the most hipster hat of all hipster hats.
Noted, thanks for your input
@@BostonWhoFan515 All good! Just having fun ourselves haha. I have played the 3 series, it's a great fuzz at a great value. Thanks for being a subscriber and a Stringjoy Player!
@@Stringjoy see, you guys rock!!! 🤘
How will dying battery pedals in front of Fuzz pedals work for bias.?
Please bias some jfets for us!
I want expression pedal control of the bias; anybody doing that?
👍
Blackstar… all you need.. my BIASED opinion 😅🎸🎶😎
Bias fx fuzz pedals
The fuzz is my favorite type of distortion even though I'm a shred and sweep player, but the actual fuzz face is one of the crappiest fuzz circuit architectures around lol. I'm nowhere near the Phd level, but my formal education is in electrical/electronics engineering.
That crumbling you hear is the transistor stealing some of the guitar's input signal to bias and switch on. You're literally hearing another cause of it's distortion generated by the loss of input signal and the transistor clipping it just as it's switching on and off. Both are audible traits. That couples with the "organic" clipping created by pushing the transistor into the top of it's operating specs, so it naturally clips the signal.
It's a highly non-linear circuit.
It has it's highlights that make it unique, but overall, it's a rather low quality circuit and effect. People do things to improve upon them, but the low input impedance, and the biasing that runs them in a sloppy "Class-A/B" sort of way makes them a gimmick by an reasonable and modern standards. It's great for some genres of music, but if you're looking for outstanding note definition and separation such as when playing very clustered arpeggios, it's literally the worst fuzz you can choose from lol.
I'm about to finish up a very high input impedance Class-A fuzz, but have been battling with myself over adding clipping diodes. An authentic fuzz is generated by running tubes, transistors or a member of the transistor family at their peak spec potential, and generating the clipping.
*Anyway, when you hear a fuzz that's actually Class-A, they sound phenomenally better than these crude topologies whether it's the fuzz face, based on it or otherwise.* If I were playing punk, grunge, acid rock etc. then I'd probably be into a modified version for sure.
