You have created a forum thread about a guitar pedal and for someone inexperienced he must go through a schematic, a tale that explains the of board connections [really a text? its like a hunt for treasure] and a pcb design. Come on guys.... you know an image equals a thousand words, how hard can it be for someone that built the entire thing to spear a couple more minutes and enlighten the rest of us that know not so much on electronics.....And after two or more requests through the hole thread that ask for clarification on that subject and the answers we get is that: i posted all you needed in a past page..... If what was there was enough i wouldn't ask for something more.
With all the respect, and knowing that i will get attacked by some of you [and also knowing that most of the responds will be you shouldn't start building the effect if you couldn't figure it out]. please help...... with a complete image of all the connections [even if they are poorly drawn on a napkin or toilet paper]. thanks
:shock: :applause:

... :slap:
Very helpful response. You must have felt very proud writing that here. Please don't forget to give your useful advice to other fellow forumists that need it. Thanks again!!!!!!

hey guys,
I designed this layout, I checked it following the schematic several times and it seems ok, but if someone wants to look at it would be helpful!
I hope you like it!

and this is the second PCB side, for those who don't want to use the jumpers and is able to make a double-sided pcb!
note, don't forget two little red jumpers as marked in the layout, those remain!
there are the links to pdf files of two pcb sides.
enjoy!

I don't know how interesting it is at this stage but I redrew the schematics in a way that makes more sense to me. I hope you will find it interesting.

I put together a slightly different version of the Blackstone.

- It can be set with: one Red channel+one Brown Channel or two Red channels or two Brown channels.
- The two channels have independent tone/mids controls.
- There is a buffer on the output stage to lower the output impedance.
- LEDs show the status of the pedal (on/bypass) and the active channel (CH1/CH2) independently.
