Ok, I'm not really one to reverse engineer pedals but this one is too good to pass up Also, I can't get over the fact that NOBODY has attempted this pedal yet!?!? Soooo... I bought one just to rip apart so we can all have some fun... Well, really it's for me I'm not gonna lie I have already traced the pedal but I need some help with the schematic (I really suck at making schematics) I can read them just fine but making them from a trace is another story... So, if you would like to help either post here or shoot me a PM. If not, I will go it alone

Reasons why I chose this pedal;

1 - It's BRAHUUU_TAHALLLLLL!!!  
2 - It has some interesting features, noise gate that tracks the gain knob, tight attack control, mid/thrash switch, pre and post fx loop that tracks the On/Off footswitch...
3 - Some of these features can probably be incorporated into other designs.. good learning!
4 - Looks like it's using very easy to get common parts.
5 - It's BRAHUUU_TAHALLLLLL!!!  

If you have never heard of this here are a couple vidoes...





Here is a teaser... If anybody is interested in this then respond and I will upload my traces!?

https://www.dropbox.com/sh/x2u0g6jdhtik5i4/_Sb3kXUSht

Ummmm..... yes please, upload traces   

Slightly off topic...

One of my few brushes with stardom was getting to know Mark Kloeppel.  He is a nice guy.  I tried to grill him on just about anything I could ask.  I wish some of that information was helpful in this thread.

Good luck with your investigation into the pedal.

Anybody?

brave man..

I can't believe no interest here???    wow!

Oh well, here goes nothin.

No on-board pots and no silly LED light up knobs... All the rest is there!

By the way, this is NOT Verified, yet! Don't be a sissy... Check it yourself, and maybe build it if you dare!  

I fully expect that this will sink into the abyss of this forum, prove me wrong...

Your ground trace forms a ground loop around the perimeter of the board.  It will hum like a SOB like that.  You need to break it somewhere so the current only has _one_ path it can flow. 

I may not build it but I applaud your work on it.  Nice job.

Good point!!!   Thanks for the heads up!

The pics and layouts are corrected in the original post, loop broken on far right.

Thanks to defaced for the catch!

Here is the bill of materials if needed..

looking good! Curious about the bass version now... ;P

Not my bag but it's an interesting looking design, some nice snippets in there. Nice work tracing it.

I've taken the liberty of putting together a BOM for this project:

I wanted to make a single sided with no frills... I see you beat me to that Jok3rx... It would have taken me forever anyway since I have so little free time...

jymaze,

Well, mainly YOU and bajaman did all the hard work and came up with the schematics! Many thanks!!!  This was a beast to draw schematics for in my opinion, very erratic jumping from one side to the other...

As for "no frills" I personally would have liked to leave off the loops but figured somebody might want them...

Great job by the way! 

Well, the schematic is verified anyway... good work jymaze and bajaman!!  

I don't know about my layout but I believe the schematic is 100% correct!
