"I know I've made some very poor decisions recently, but I can give you my complete assurance that my work will be back to normal. I've still got the greatest enthusiasm and confidence in the mission. And I want to help you."

This build is a tribute to one of my favourite movies - a true cultural masterpiece -  Stanley Kubrick's "Space odissey 2001"
I'm getting tired of home-brewing PCBs, but sometimes it's worth building it "right now" than waiting
Yea, i know that building some delay/reverb could have been more suitable for this role, but i wanted no pots on the enclosure)

"My God, it's full of stars."

Great build, very well done, hard to believe it's the first! 
You might want to consider soldering at least one leg of each transistor in the sockets otherwise they might fall out, most likely when the nicest and most critical part of the guitar solo is about to start.

Not the first pedal i built. The first, that was built not for myself, but for my bandmate)

Thanks for the advice about transistors! I will definitely fix them, as soon as i recall this one to place sorted by hFe transistors in)

Woohoo! I just completed my first effect, built by request. And it sounds totally awesome! I would recommend it to anyone who love big muff sound, low tuning and stoner music) Basically, it is  modded Ram's head BigMuff. The Hi control lets you compensate the loss of highs while turning TONE knob down. The upper switch toggles between germanium, silicon or no diodes in second clipping stage. The lower switch gives a slight input level cut/boost (I think, i will replace it with a footswitch)

Many thanks to Effectslayouts for etching template!

Hi!

I completed some builds wich allow PCB-mounted pots, but all pots i have are short-lugged, so mounting them as is = placing pot shaft in parallel with pcb. What is the best way to mount them vertically? I tried to solder extra lugs wich were cut from soldered parts, but it seems not very firm and reliable. I thought about etching some small adapter boards with 3 tracks and 6 holes (with l-shaped connectors on one side). Is there any less tricky solution?

You can coat it with tin right after etching. You can use regular solder, or something special, like Rose's metal alloy (it melts in boiling water, very useful for tinning)

This is for 7805

How many legs does your regulator has?

You can convert any so8 or sot89 to to-92 by soldering pins to it, just read pinout carefully

Respect!! I tried 3 times to make a way more easy schem on perf board, but every time I messed it. And yours looks sooooo dense...  And yes, do you have a photo of another side?)

Wow

I really like the switching clipping stage
What effect does 2 diodes in parallel to the ground produce?

I want to build something like this, but with switching between diodes and FETs, something like Fulltone FullDrive 2

here you go. It fits in 125b enclosure.

Thanks for the feedback, guys!!!

Is this about the jfet or is some mod of the schematic.

I never tried to compare his schematic with any other. as far as I know, he re-worked the tone stack.
the original is also JFET,  J201 or 2n5457, or 2SK170, or КП303А - I think the guy who draw schematic that I used just took whatever was cheaper) The important thing is the value of of current on drains - it should be 4.5v on q1, q2, q3 and 5.5v on q4 to achieve a tube-like sound

If you're interested, I can share a project, I just don't know if it is correct or not to post links here)

This project is verified and sounds totally awesome to me)

Hi!
The sound of this pedal resembles  the sound of my favourite guitar amp - Mesa/boogie Dual Rectifier.

The schematic is popular "dr.Boogie", based on 4 FETs (in my build, post-soviet made "КП 303 А"), modded by AlexZ (he also made a pcb transfer image)

The pcb is home-etched, the artwork is printed on transparent ink jet film

I know that the artwork contains copyright-protected images, but I build this only for myself and do not seek any commercial purposes. All logos are placed there just for fun)

Could you please post proportion of acid and peroxide? (and whatever else used to etch aluminium?)

may the klon be with you

what did you use as an etchant for the enclosure?

Acid magic and peroxide. I etched a board the same day, so I used it for the enclosure too. I like it, I'm gonna keep using that combo.

an "acid --" what?))

smthing like this? http://www.certol.com/acidmagichome/

First want to thank persons like Madbean and Storyboadist, who make DIY content absolutely approachable for total beginners, like me)
My name is Sergei, I'm sound producer/guitarist from Moscow, Russia.  I never had enjineering education, but i always wanted to create stuff that sounds)  About a half year ago i drew (with a permanent marker) and etched  my first board,  it look totally creepy, but when it started working, i realized, that from now i have a new hobby)
