CONTEST What? Another Contest?

CONTEST
Here is my first submission. Below is the schematic labeling the part numbers as seen in the Muffin Fuzz build doc and their values. I've also included a pic of the breadboard just in case. This is a nasty little octave up fuzz. The third and fourth transistor stages have been removed and you will need to jumper from C7 to the volume pot. I call this circuit the LUNCH CRUNCH.

Edit: You will need to adjust your guitar's volume pot to taste. I wanted to put a pre-gain in here, but chose to go the lazy route :cool:

Going to have to give this one a shot!

I'm thinking that if you assemble it on the Muffin board you could shift it over to the second and third transistor stages (omitting the first and fourth) and use the Sustain pot as your Pre-Gain.

Right now I’m just using the basic topology of the circuit. I need to start thinking outside the box for how to put it on the board. I’ve currently got an overdrive-esque in the works. Will finish it up tomorrow hopefully.

This is fun!

That was quick! Very clever, very clean.

Daaamn, nice. I haven’t even had an opportunity to break out the breadboard. I have been thinking about it and looking for that aha moment.

I have my first idea in motion. Well it wasn't my first idea, that probably happened years ago...and really, it wasn't my first idea for the challenge so, I guess it's just another lame idea, but it's in motion so there you go.
 
Here's another one I cooked up between last night and this morning. The main sound I got last night and finished the TONE control this morning. This one is a heavy overdrive/fuzz circuit I'd like to call AIR NUTZ. To build this one the board you will need to bypass the third transistor stage. To make the TONE control (it's really a BRIGHT control, but I'll stick with Muffin terms, LOL) better I added a 820ohm resistor to ground after the TONE knob. I've designated this one R200.

I want to see what you all can come up with too!! I'm not drooling over Chuck's fancy breadboard (though it does look rather tasty), I'm having a blast just making my own circuits!

For anyone thinking this is a bit too challenging or doesn't know where to begin, here's some tips that helped me:

-Look at the Muffin Fuzz schematic in the build doc. Print it out. Remember how this circuit is laid out. This is your starting point.

-For "inspiration", check out many of the other Fuzz and transistor-based distortion build docs here on this site. Take bits and pieces of circuits and mash them together here.

-You don't need to use every component in the schematic. Certain parts do certain things. Here's the circuit analysis from Kit Rae.

How many boards did you buy @BuddytheReow ?

I need more boards! I'll just buy them out...yeah, that's the ticket!

I have only ONE muffin fuzz board sitting in a drawer...

That being said, I do have the schematic printed out on my workbench that I tell myself "yea, this could work if I just bypass this whole section". I also ask myself questions like "There are 2 diodes here. Can I just put in one instead? How does it sound?". "Instead of a 100n cap, what happens when I put in a 10n instead?"

I've gone from my workbench to my amp and back at least 2 dozen times in the past 24 hours, LOL
 
This is also to help anyone who needs help think outside the box.
@Chuck D. Bones this is up to you if you want it to be a submission. I'm just having fun at this point.

Starting at the SUSTAIN pot I kept the pulldown resistor in there (R23) you will have to add a jumper to it. I then copied the second transistor stage using many of the common values found in the build doc for the Muffin Fuzz. After this stage I put in 2 diodes to ground. I put them in place of R13 and R16. You'll have to add the jumpers from c7 and the Q3 holes to complete this. Then it's a simple BMP tone stack (pick the one you like best), and then I chose to put the recovery stage as a LPB-1 rather than following the build doc.

It's a basic distortion circuit I will call the MUFFIN STUFFIN. For more transparency, I added some yellow jumpers on top pointing to where jumpers on the Muffin Board need to be done. This is all theoretical of course; I'd rather breadboard all this crap than whip out a soldering iron for circuits that may not work or like.

Here's a peek at what I'm working with. Trying to get the bias right on everything so far. I'm thinking of changing Q3-4 to FETS and redoing the whole back half. Right now it sound pretty decent as a massive, endlessly sustaining fuzzstortion, but I'm really looking for more low, spitty growl. Being new to this I've never figured out how to get that sound yet. This is essentially a Zonk into stacked Electras.

Right now I'm just sticking with BJTs. FETs are a different beast that require more controlled biasing IMO.

Very true, although I saw a Big Muff schematic with BS170’s and very minor changes which surprised me. The audio sample sounded pretty decent.

Here's my last one for today, I swear. This is is a modified Bazz Fuss (just google it. Stupid simple). Start right after the SUSTAIN pot. Only 2 transistors are needed here. The diodes really make or break this circuit. I chose to use a 5mm green LED for D1. For D3 you can either put in another green LED to make it a heavy fuzz or put in a different one (I used a 1n4007) for a nasty Octave up effect. I made this a bit more bass friendly by using 1u coupling caps so @peccary this one's for you! After the circuit there is a switchable output cap which really controls the bottom end. @Chuck D. Bones is this allowed. Then the volume pot to your amp. My breadboard has the second green LED mentioned above.

Since it's a modified circuit I will call this one the BASS FUXX.

I have tried a similar circuit in the past, it sounds pretty awesome! Nice work.
