Funny little boxes

[Mikey]

so  I  built  this pedal  according to  the  board  codes but the schematic doesn’t have  the second  gain stage.  The pedal doesn’t  work  it has through signal  but turned on it has nothing  I omitted  the 4.7 clr and populated it on a breakout as well as  the  led do those need to be in the circuit  for it to work ? Anyways  was just hoping  to get an updated schematic  really

Which Funny Little Boxes?

1991 or DIRT.

Keep in mind I am not the designer and they only come with what is provided but all of them have been built by someone.

If it is DIRT someone on the forum as I recall has built that one so you could look at theirs for help using the search.

I am only guessing here but if you are referring to 1991 (Pearl Jam) which has two Gains this is the schematic from that build document.

Both Build documents are available on the Guides Page:

Nope not same  build his just has the volume  and dirt potentiometers mine has the 3 so 6 potentiometers volume mid bass treble gain 1 and gain 2 stages. So not the same  the board says funny  little  boxes dirt. But It’s not the same  build.

Hopefully that takes care of it.

I am printing  those build docs now  so I’ll give it a run through

[Mikey]

Thank you berry

[Barry]

The builds are nearly identical aside from the added potentiometer.

[Mikey]

Pretty  close yes

And I found  my mistake  I used a capacitor code instead  of placing a 100 ohm resistor  lol. So I have a 10 pf in that place haha
