 Buid pics. You find the schematic and the PCB in the attachment.







In the video is the pedal on the left, on the right is a Triple Wreck. Sorry for the quality but I don't have a good camera and I'm not a guitar player.

 Thanks guys!

 Well, EP Booster.
I placed the +3dB and Bright switches on top of it, each one has an extra mod: middle position - off, up - factory mode, down - extra mod. To be honest, not much difference, especially at low volumes.

Romania!

Its tough getting Ferric Chloride spills out of a white bath tub!

Yeap. Problem is that even after you wash it down, you can see the stains only after the bath tub is dry.

What kind of putty is that?

I don't know. It's important that it's not soluble, so the Fe2Cl3 won't wash it off.

Really cool pedal and etches! 

Thanks!

How did you get such a clean etch on the board?

Cheap photo paper and laser printer.

Did you heat the ferric chloride at all? How long did it sit in the chloride?

No heat at all. Concentrated (or heated) Fe2Cl3 has a nasty reaction in contact with the aluminum, this is why i use overused Fe2Cl3. I don't have an exact recipe, but the reaction must be slow. If it starts bubbling slowly after a few seconds, i'm on the right track. Let it etch for 2-3 minutes, pour out the Fe2Cl3, check the depth of the etching and the integrity of the adhsesive paper. Pour "fresh" Fe2Cl3 inside and let it etch for another 2-3 minutes. Depending on the design and the concentration of the Fe2Cl3 i do that 2-3 times.
As i said, not an exact recipe, you need to experiment this. You may use another etchant, like NaOH, but after an accident involving my wife's shoes i'm banned for using that.

Great looking pedal! Thanks for the pictorial link. Could you explain a bit more? Are those water slides for the toner? Is that modeling clay to hold the etchant? Ferric chloride? How are you cleaning out the etched areas?

Really great stuff! Thanks,

Marty

  It's not water slide, it's a cheap (around 2$) adsesive paper used in constructions to protect surfaces. You can see it in the 4'th photo.
  Not exactly modeling clay, it's actualy my kid's play dough
  Yes, I used second/third/fourth hand ferric chloride. It's the chloride i used to etch PCB's.
  Cleaning out the etched areas is kind of tricky, don't actualy have a good method for that. I use ordinary kitchen stuff and/or 1000/2000 sand paper.

  It's the cheapest method around, i used ordenary household items and used (actually overused) ferric chloride. If you draw the design by hand you don't even need a printer.

I used the etching method described here: http://www.madbeanpedals.com/forum/index.php?topic=23062.0

  I also included pics of the ething method i used. Kind of time consuming but deeper then the toner tranfer method.

























And a small video with the pedal. Again, i'm not a guitar player, so...

  This is one of my early builds. It's a BB Preamp and a JHS Minibomb in one box. They can be used separately or together.

Very nice !  Did you design your own PCB?  Or if not, where did you get the layout?

It's my own layout, I can post it later if you're interested. A small video, clipping and tone testing. Sorry for my guitar skills , i'm not a guitar player.

 It's a modified Pharaoh Fuzz. I did't like the Pharaoh tone control so I put a Baxandall instead. To compensate I replaced R24 (see schematic) with a trimmer. Also, it has 6 clipping options (the 6'th it's ... nothing connected).

 Well, I only breadboarded the Dr. Boogie and it's noisier then the 3W, but it might be the breadboard wiring. Also, the tone controll on the 3W works better for me. This was a tight build, I made 3 of these and I don't think I'm gonna do it again, it's too much trouble. I prefer larger enclosures for this:
