Death by Audio Germanium Filter
A while ago. Chris Stelloh sent me a Death by Audio germanium Filter to trace. The trace went pretty smootly and I sent the schematic to Chris and he made a vero layout out of it. However, this circuit requires some transistor and diode picking to work as intended. See Chris's notes below...

Capitalist Death Cult No One Wants To Work Anymore
Taking a break from the Madbean bonanza since Chris Stelloh sent a layout and a schematic of one his creations. Some words from the man himself: And yes, this layout is verified.
Here is something I came up with recently that shakes the pillars of heaven, via WAY TOO MANY cuts and jumpers.

Madbean Dinky Drive
Schematic can be downloaded HERE.
Based on the pre amp section of a Bad Cat Mini II which is supposed to bring some "Voxy" tones.

Madbean Stank
Madbean pedals was a great resource and very educational when I started out with DIY circuits. The archives with old projects is quite impressive. So the next coming days you'll see some Madbean content (some well-known, some obscure). Let's start with something simple...STANK!
The schematic can be downloaded at Madbean Archives page.

EarthQuaker Devices Organizer
Chris just sent me an another Spin FV-1 based layout. And he verified it.
"This is a layout for the Earthquaker Organizer Polyphonic Organ
Emulator that I drew up using the Pedalpcb schematic. Two things about
this layout (which is verified - I have all ready built it):
1) it addresses the volume drop issue that was common in early traces of
this circuit. The pedalpcb board now has a 20k trimpot to solve this,
which I have simply converted to the 20k resistor that is on pins 13 and
14 of the quad op amp.
2) you will need some supplies - an FV adapter and the EEPROM with the
algorithm - which I would recommend getting from pedalpcb. PCB Guitar
Mania makes a clone of this but I did not see a listing on their site
for an algorithm chip or an SMD adapter. The FV-1 adapter board that
pedalpcb makes is quite easy to use and I would also recommend watching
DK Pedals' tutorial on YouTube for soldering the FV-1, as it was very
helpful to me. The EEPROM algorithm chip is available for about $6.00
and if you search 'Organ Donor EEPROM' you will find it. It is not
listed on the regular EEPROM menu. Also - 2x14 rows of pin headers will
be needed to go between the adapter board and your vero."

Frost Giant Electronics Black Gold
Traced by moushh.
This thing looks quite wild. With the gain control set at minimum, you have the stock Acapulco Gold gain setting. Turn it up and you'll have much way much more gain avaiable... The Bright control is an welcome addition, a simple adjustable low pass filter.
