Here's my recently finished machine. As a nine inch nails fan I named it the "Pretty hate machine".
First time I'm using a madbean fabbed board, and it's really a pleasure to solder!
It worked perfectly once I've finished the soldering.
I love that cool effect I'm now using with my kokbox. It adds so much gain, grain... Perfect for grunge, industrial, or boosting your solos! A unique sound under the foot.
Sorry for the poor pics using my iphone.
Thanks Madbean for such great PCBs :D

that's a pink box alright...
good work.
Cool ;D
My wife always asked me to order one of those hot pink enclosures from PPP. Thought it would match with "pretty hate machine" 8)
Thats rad! Bet it sounds great 8)
I heard of people getting low output of their diy machine, mine is really loud ;D
I used some fairchild Bs170 I found for cheap on ebay :

Nice job. What pot did you use for the trim knob? Today I ordered the last parts I need for this build- I'm excited as it will be my first build. I ordered a 1k and a 2k so I could test and use either. Cheers!

Like the BOM on the pdf, I took a 5kB linear pot. I'm happy to use it as a pot 'cause it really tweak the sound. Opening the box to adjust a trim in that case is a bad choice.
Good luck for your first build! We can help you if you have some problems ;)
I just tried the machine with the retrograde, and using an octave effect with it sounds really cool!
This is an endless entertaining machine :)
Hah, you used a 5k- I was going to order an extra one of those yesterday but removed it- I will have a 1k and 2k to experiment with. Also, I have been looking at every page of this thread (awesome stuff) and am wondering if I should socket anything like transistors or diodes to play with. I see a lot of other folks choose to socket stuff. What do you think?

In the case of the machine, I don't think that changing the diodes can radically change the sound so you don't need to socket them. On some other build (with diode clipping) you can socket the diodes to play around with other ones, or switching 2 or 3 types of diodes with a toggle switch (like in the uproar or the sunking eleventy bajillion).
Socketing the transistors is usefull to avoid overheating during the soldering.
If you plan on changing a transistor of the BOM by another one, read the datasheet of the transistor first.
There are different types of transistors, so their pins are not always in the same order, so it changes the place of the pins of the pcb. They can also have radically different HFE.
Be carefull with the Bs170, they are static sensitive.

I've been meaning to ask, how do you go about dealing with this?
I am a freelance computer IT, and as far as I know when dealing with static you just need to touch a grounded conductive object before handling the parts. They also make wrist straps with a wire and alligator clip to keep yourself grounded (hah) I also used a static/radiation filter when I used to use a big CRT computer monitor- it had a wire and clip as well that you would attach to the computer chassis or other ground.

I also have to say in over 10 years of working I have never had an issue- just touching a grounded object first always seems to do the trick.

Yea I saw that with a quick search but it says that wristband must be grounded, so I'm guessing they mean the ground in my house? I'll keep researching and report back.
This is why they wouldn't give us CMOS chips to fool around with in school...
The wrist strap to computer chassis I think assumes the power supply is connected (3 prong grounded) which is connected to your house ground.

Awesome pedal! I have a pink flanger... its my statement of self assuredness ;)

I have been grounding myself with a wrist band though my amp... (Has an earth pin) Basically plug the guitar cable into the amp and cable into an alloy mounted socket on my proto board which I clip on to. Not a pro setup but works good... I've had no problems even when handling a particularly sensitive 4001 CMOS chip by hand for a non pedal project. You are earthed through the guitar cable>amp>ground
This is a good way to do, but I dont own a wristband, so i touch the amp chassis before taking the tranny in my hand. Think I'll try wearing surgical latex gloves in critical moments :P
I talked to my neighbor who is an EE and he told me an amp would work if it has the round ground pin, but not to always trust old vintage amps because the ground could have been lifted to help eliminate hum. He said my computer would work for grounding, just gotta touch one of the metal screws in the back that are attached to the chassis itself, NOT THE PAINT! ;D
So if you use an amp you wanna verify that the ground is attached. And he also said the house must be properly grounded which I'm not to sure about in my case ::)
Oh dear. Get a socket tester man... I got one that cost $20 and tells you whether the socket is earthed or out of phase... You should test all your power outlets if you have any doubt on the wiring in your house
$2 for peace of mind and an intact central nervous system! ;)

I haven't checked my house yet. The wall socket is different in France and I haven't found a tester for less than 80$... I'll think twice before buying :-\
What kind of effect machine is? Is it a booster? I didn't understood the description on the official site...
This is effect is unique. There's a boost in signal (the pedal does include some Supe Hard On stages), it adds a lot of dynamic, the sound is less articulate and a bit harsh. If you like grunge or industrial metal, you'll sure find it to your taste ;)
I'm pretty sure Robin Finck of Nine inch nails use it live.
The effect is to be used with a distortion or a fuzz, not on clean sound.
Watch this :

I've noticed this effect does do a lot of stuff, but the most unique feature to me is how it causes notes to bloom. Sorta like an old Superlead or cranked up tube amp. With double stop bends this thing is the gnarly!
Ok, thanks:)
And how about noise? I think that distortion+distortion give many noise...
I don't have to bother with noise actually. Using shielded wire is not necessary with it ;)
