am lucky enough to build a fuzz for one of my all time heroes, the legendary dick wagner...

so here it is, schematic and vero layout, both verified...i've built two of these things, one for me, and one for dick. it's a nice loud ballsy overdriver, capable of overdriving
the front end of an amp hard, with varying levels of distortion right up to fuzz. i was playing with diodes and resistors, you'll notice that there's a couple quirks, like the 2 10k resistors in parallel...and the ge diodes...

This is how I'd do up a Bazz Fuss if I were going to sell these for $250 as a boutique product. :thumbsup

Why use a darlington transistor when you can use two common BJTs?

Why use a simple diode for collector>base feedback when you can use a MosFET's body diode* instead? MosFET = more $$$ from more exciting marketing!

So we've got three transistors that could be doing the work of one + a diode. Brilliant!!!! :lol:

I made up a totally unneeded two-side layout for it as well. :mrgreen: You...

Some of the values need tweaking a little here and there to take into account differing output impedances but this has a great basic sound! As far as I know this is the first time an all Mosfet Big Muff has been built? As you can see the tone response is based around Skreddy's Top Fuel. My idea is to build this into a standard size enclosure with just the volume knob on the outside, the sustain and tone controls would be internal set and forget controls.... Stick it on your breadboard and have...

Each year, I build a short run of a new design of pedal for a few friends and colleagues. These are given away as Christmas presents, though some of my regular customers insist on paying for them - the money always goes to charity.

This year's project was built (originally) for the single-coil players amongst us, and was (essentially) a modified Orange Squeezer. The modifications include an optional input buffer, an output buffer for lowered output impedance and an altered filter for the DC...

Tried out the MFZ-1 on breadboard today - it was ok. Swapped some parts to try out the Hidrosis (posted at DIYSB about five years ago by brett) and I preferred it. Gain pot ( sweat ) does something quite interesting, with a quite woolly sixties sounding fuzz at minimum, becoming brighter with higher gain but also more body+definition, almost like some cleaner guitar is getting mixed in, weird as that sounds. Knocked out a quick vero, unverified, but looks ok (please cast a cautious eye over it...

Here is the schematic for a crazy device I knocked up on breadboard. It's a Cannibalization of the Parallel Universe from eaced.com, the big muff tone control and the lofi delay created by Allesz for last months circuit competition. It's a truly unholy circuit and creates all sorts of screaming, oscillating, feedbacking (is that even a word!?), beeping, buzzing and whooshing sounds.

Some of the values need tweaking and it could do with an output buffer but for what it is it's great, just pure...

Going through an old hard drive, I found this old circuit. The PCB layout is attached, and the schematic will follow when I clean up the scanned pencil scribbles from the notebook! It was designed for commercial production, and ended up as a project in The Maplin Magazine , and never made it to manufacture.

It's a great sounding wah - with two peaks in the response that are slightly offset to broaden the peak. The noise reduction really works well, too.

Enjoy!

I know there's a bunch of dr. threads, but don't think this one fits in with any of them, so a new one begins..

decided I wanted to try a doc in a 1590a, but it was never gonna fit, so I picked up some smd trim pots off ebay and made a layout for the doc. and proved it 'works'.. the treble and bass pots don't do much, but think that is cos of the rubbish speaker in my ruby test amp... I hope at least. it's kinda hybrid since only the pots are smd...

anyway.. here's the stuff..
layout:...

I doubt anyone wants or needs this, but seeing as I bothered to draw it up, I might as well share it.
This will fit in a 1590a, but then again pretty much any WM build will.
Still, this replaces pots for Fuzz and Gate (Wool and Pinch) with onboard trimmers. Typically I find these are set and forget.

Also are instructions for a switch for subs like a Mastotron.
This is built and verified. Thanks to |v|ark for his original layout.

Can't add the files to Freestomp Café subforum where Weird circuit topic ware started, so I'm doing this here

From the Electronic Secrets the professional pedal designers keep to themselves file:

The current it can usefully pass is limited to (perhaps) 20 mA, and it won't fix a faulty 9V adaptor, but it really can cure the hum you frequently get on high gain fuzz effects!

Hi guys, this is ANGRYDRIVE v1.0 my first design/mod based on BB Preamp. I decided to gave it a new name because it's sound different than BB preamp. This pedal got more hair but still can achieve nice and warm OD. So without further ado, here it is.. :)

Sound samples are coming soon..Enjoy!

Cheers! :mrgreen:

See attachment for a full package to make your own Arbiter Fuzz King.

Which one?
(thanks Discofreq)

- Verified? Yes ofcourse.
- Questions on building or debugging? Ask them here. Not through mail or PM.
- Comments? Yes please. Always working on improvements!

Hi,
I found nice overdrive. Sound demo like :

Hi everyone,

Not really an effect of course, but useful and ready-to-build as required. I've made this one some weeks ago, and I've just cleared up and tidy the work file to share a fully explained PCB layout. There are vero layouts and most probably PCbs already existing around the internet, but this one fits a 1590B with the PCB held vertically by the pot.

It's obviously based on RG's Quick and Dirty Oscillator .

I've made two add-ons that aren't specified on the layout:

- two banana...

This is basically the phase 90 from tonepad with some of the mods integrated from BYOC on perf. I am really digging the vibe and phase sounds on faster settings. Though for a in your face slow phase, you might add on 4 more stages via daughter board. I will probably do that for the next build and throw the layout on here too. I used MarkM's jfet matcher also.

New shit!
Layout for small box Fuzz Sound - FZ-75(JR). Enjoy!

This project was an outgrowth of my FSB contest entry, the Wobble Vibe. I added two more identical phase shift stages for a total of three. I also added a rudimentary feedback/feedforward control (which actually *sounds* like a Depth control) and adjusted the LFO a bit to even out the sweep and give it more speed range.

It's part phaser, part filter, part tremolo, I'd say. The variable resistance elements are LDRs, all three run by a single LED fed by the LFO.

The LDRs I used were the same...

This version have two options of assembly - for single and dual supply polarity.
Construction allows you to add it to existing design simply by drilling hole for the output jack.

Hi to everyone,
today I posted a new project on my website, after four years of silence...
I took a standard Double Muff and added a lot of features, such as individual gain setting for each amplifier stage, a tone control, output buffer for volume recovery and a trimmer to avoid volume difference when switch between modes.

In case of copyright issues, I'll remove it from my site, but the design I posted is no longer a standard Double Muff...
Bye and have fun
Alessandro

OK, I had posted up an idea for a line driver/buffer a few months back, but I screwed up something in the design and it didn't work right.
Anyway, I finally got around to re-thinking the circuit, and now I'm proud to present this Line Driver/Buffer/Preamp that should solve many problems for you.
This circuit is fully verified and sounds wonderful!

I built up this first one on a simple perf board. I don't have any layout drawn for it, but it's a simple enough circuit, I'm sure you can figure...
