So, yeah...five knob Fuzz Face build. Someone had asked me about using BC209C transistors and I’ve never really built silicon Fuzz Face projects. Pretty much always germanium. So I decided to experiment. Usually with germanium the common wisdom is for Q1 to be around 70 hFE and Q2 to be around 130 hFE. Silicon transistors are way hotter. This has a 400 hFE in Q1 and a 528 hFE in Q2. Sounds cool to me. Cleans up with the guitar’s Volume knob like it should. Maybe the ratios are more important than the voltage.

Man, not to short-shrift my DIY paint job on the Fuzz Face to the right, but this Candy Red Vein powder coat job from Pedal Parts Plus is some kind of freaking awesomeness.
It's going to house my Brassmaster prototype. Well, the case looks awesome. Let's cross those fingers for the circuit.
I have something to say first. I *ate this pedal. Very very noisy, and the sound has withdrawn to the interior. At least in my environment.

I needed to put a fresh battery in, so I figured I'd get a "gutshot" for the pedal fans.
This is the FuzzFace clone seen here elsewhere
Here's a picture of a 2N527 Germanium transistor sitting upside-down next to a socket to show how easily you can identify the pin outs of most transistors. Not all. There are a few with reversed pin outs, but not many. Usually you just match triangle to triangle and you're good. Those sockets have spring-loaded retainers that grab the legs nice and tight so they won't go anywhere once they're in the socket.
Neat and tidy didn't last long. I picked a pair of transistors, plugged it in and nothing. There was a tiny bit of solder on the bottom of the board grounding out on the standoff. So now you can see my single-standoff mount.
So yeah, a 70 hFE in Q1 and a 129 hFE in Q2. Both AC128 Germanium transistors. Sounds like a (hot) Fuzz Face. On to the mods!
I'm not the first to try this, but I found little info online so I had to come up with my own.
The Fuzzface side should be faithful to modern silicon Fuzzfaces as it is practically a clone, using even the same bc108 transistors.
The Tonebender side is much angrier and louder. I do not know how similar it is to a Tonebender, but other than the transistor it is MK2 specs. It is a cool flavour in its own right and still cleans up with the guitar volume, so it's good enough for me. R4 is crucial in making silicon transistors work in Q1. Tonebender diagrams are usually for germanium transistors that don't need R4 at all. That caused me a lot of mental pain and a bunch of burnt components...
Q1 collector voltage is adjustable by internal trim pot. Diagrams call for 10K, but for me that was sputtering too much. Adjust to taste.
Q2 collector voltage makes little to no difference as a trim pot, so fixed 33k is enough.
Q3 collector is best as an external control. It's fun to mess with for that starved sound, but also important in switching between the two circuits. Fuzzface likes it at 4.5V, Tonebender likes it at over 8V.
I've seen different values for C8 between the two, going up to 104, but I was out of room on the switch so I kept a common value of the less bassy 103.
Oh, and it has all the bells and whistles, like true bypass, battery or cable supply, LED indicator, reverse voltage protection and pop elimination .
It should also work with C1815 transistors, common in asian-made electronics, but you may want to install treble cut capacitors (smaller than 101) across collector and base on some of the transistors (values and number according to taste).
Two old germanium transistors and one silicon transistor and the great sixties sound

There was always a wonderful look of enthusiasm in her eyes when she first realized that you were holding her ball..
This is a silicon Fuzz Face-style circuit with a Mids control that's very similar to the Fulltone '70 pedal.
It runs off either 9 volt adapters or an internal 9 volt battery. Powder coated for durability and with a true bypass footswitch to prevent it from sucking tone when you aren't using it.
Built using a pair of BC108A transistors mounted in Mill-Max sockets, so if you want to put your own transistors in it that's easily done. There's an internal bias trimmer. I have it set for about 6 volts, but if you prefer a different biasing you can easily adjust it yourself.

Ozzie was put down today. Oh, it was horrible, I cried so much, it makes me so sad whenever I think of it...which is a lot.
Just going to the backyard isn't the same without.
it seems so surreal, like I'll wake up tomorrow and he'll still be alive.
:'(
RIP

best dog in the world.
OK, the first logical step to making sure I'm doing what I want to be doing is to strip things back to their essentials and make sure the fundamentals (no pun intended) are where they should be.
For me that means voicing. Now, I know I'm going to rely on the, "Hendrix" mods for gain, so that's retained in this build. I replaced the tiny Output Cap I had in place with a more substantial Philips, "Chicklet" cap. Same value, just a high-quality cap. Just to make sure that component quality isn't a factor.
The Bypass Cap continues to be a Roederstein, "Golden Bullet."
I plan to start by messing with the Input Cap values to see how that influences the overall voicing of the circuit.
You may have noticed that the Treble Bleed cap is missing from Q2 now. That will be another series of tests to determine which value works best once the Si transistor is in place there. I was using a 500 pF, but I have a 330 pF and a 100 pF that I'd like to try out, as well.
I know this is probably overkill, but I don't want to finalize this project until I'm sure I've poked around all its dark corners thoroughly. I'd like to know exactly what I'm building and feel secure that I can keep banging it out exactly the same way for the foreseeable future without wondering if I should have tried out a different this or that.

This Fuzz is that used IC. LM358N that is the operational amplifier of a single power supply is used. A wonderful sound is output though it is corrected with very few parts.
Moreover, it is very powerful.
The latest Fool Audio Research, 'Infinite Fuzz' build.
Dig the HAL9000 eye. You know, from, 'Jupiter, and Beyond the Infinite Fuzz.'
It is TUSK of EARTH QUAKER DEVICE. I think that it was soberest Fuzz as a personal opinion though several Fuzz is done in the lineup in EQD. However, the number of lovers of this Fuzz has been increasing little by little as long as I know recently.
I thought that this had passed out of print because I had come off from the product list for a certain period of time. However, it is possible to buy it usually now because it becomes the latter half of this year and it was reproduced.
To our regret, this pedal has risen. 120 dollars are 135 dollars now. However, because the quality is very high, I still think it is still cheap.
They sell new versions of these for $150. This one is probably as old as me. It was pretty sweet when it worked.
It is an internal structure of a very clean, extremely standard arrangement.
The battery was actually attached though it was not reflected in the photograph. However, I am bearing it in mind as detached when not using it for the battery. Because the battery sometimes explodes. When the disaster occurs, inside electronic parts receive fatal damage.
