Cmos big muff pi

[doomkraft89]

I couldn´t find a layout for this one.
So I tried to do one myself.
This is runoff...ves 22/7 cmos big muff pi.

Except for lots of jumpers I´m satisfied with my first layout.
Have checked it several times and it should be ok.
But since it is my first layout there´s no guarantee..
Please leave me some feedback.
Edit: Layout fixed and verified!

Well, actually, there is a layout here...

But that's OK.  I like your layout as it's narrower, and narrow is good for enclosures!

I've built this one already and it's great.  Has a very cool tone control and definitely has the fuzzy BMP sound.   It would definitely be worth experimenting this circuit.  Particularly, the diode pairs could be modded all sorts of ways (different diodes, asymmetric clipping, etc.), and you could reduce the gain by lowering the 1M feedback resistors if you wanted to tame it a bit.  Have fun!

Ohh. You see!
I search the forum but totaly forget about the main-page. o_0

Figured I would give your layout a try, due to size as well. It works great! A few things: there are two cuts on the layout side that aren't on the cuts/jumpers side. One is under the lower 33k resistor, and is unnecessary. The other is next to pin 13 of the 4049, and is necessary, upping the cut count to 21. Also, I moved the ground wire up two rows, since it isn't under a component there, and still connects to all the necessary spots.

Thanks for the layout!

Thanks for pointing that out! Find 2 other cuts that was unnecessary making the total count 19!
The ground connection was very odd placed indeed.. Thanks!

Oh! Pin 13 of the ic is not connected. So the cut isn't realy important. But I'm not going to edit it again. :) just for future knowledge! :) best regards
