Need help recreating "boutique fuzz"

[Frizz]

Can anyone tell me what circuit this fuzz is based on? I know it's a medium gain fuzz with the toggle switch in one position and a high gain gated fuzz in the other position. I'm pretty sure it's a silicon fuzz and that's all I know. It also has a knob that lets you mix in your clean signal, but I don't care about recreating that aspect of the pedal. I can post a pic of the inside of the pedal if that helps at all. Basically I want to try and recreate the circuit myself but I don't know where to start.

Who makes it, what's the circuit called, do you have any clips, or at least pictures?

There are hundreds of fuzz designs, made by thousands of people.

Anyway, if you want to trace a circuit without any guessing, here's what you do:

Take a picture of both sides of the circuit board (or just the solder side if it's an etched PCB and not manufactured). Open an image editing program, and overlay the pictures on top of each other. This is useful as a guide to ensure you don't miss connections.

Get out your multimeter and set it to continuity. Start at the input wire, working your way through the circuit to the output wire. Write down all connections at each junction. You'll want to put your meter on one component and basically check every other component lead if you want to be thorough, though practically speaking there are some that you'll know don't make any sense.

So you'll start at the input wire, and you draw this:

In >

Then you set your multimeter to continuity, and you find that it's connected to the negative lead of a 4.7uF capacirtor and one lead of a 1M resistor.

in > 4.7uF
         |
         1M

Then you find that the positive lead of 4.7uF cap is connected to the base of a transistor, which you call Q1, and one lead of a 100K resistor and that the other lead of that 1M is connected to ground:

in> 4.7uF > Q1B
       |          |
     1M         100K
       |
       G

Then you find that the emitter of Q1 is connected to ground, and that the collector is connected to a 33K and the base of Q2:
                          33K
                           |
                          Q1C
in> 4.7uF >----------Q1B
       |          |       Q1E
     1M         100K    |
       |           |        G
       G           ----------------

Then you fill in Q2 and the gain and volume controls the same way ...

                          9V
                           |-------------8.2K
                          33K           |
                           |             Q2C---10nF----Volume 3
                          Q1C----------Q2B             Volume 2--> Output
in> 4.7uF >----------Q1B          Q2E              Volume 1
       |          |       Q1E    |------|                     |
     1M         100K    |      |      Gain1               G
       |           |        G     |      Gain 2-- 2.2uF
       G           ----------------                  |
                                           Gain 3---G


You can use this method to build the schematic. It would help to number the parts as you work through the schematic. Give them your own numbering if they aren't printed on the PCB. Write down the component values.

Measure the voltages on all active components (transistors, op amps, etc.). This will be useful later for troubleshooting and for determining gain ranges.

Now use the schematic you've drawn and double check all connections.

Incidentally, that ASCII schematic I drew above -- you are 95% likely to find it in the pedal you have, though some of the values might be different.

I didn't think I was allowed to name the pedal or manufacturer. It's the Frazz Dazzler by Dr. Scientist. Thanks for the info.

In that case you are likely to find something far more clever than I posted. There's a possibility that it isn't based on anything.

Great builder/company, and super nice owner.

yes...multiple IC's & transistors
