Open Discussion / Re: The zombie chorus - it's a trap!
« on: December 02, 2019, 05:02:28 PM »
Erik spent quite some time re-engineering the zombie chorus due to the ticking problem and came up with the lich king chorus, which is a really nice sounding chorus pedal and totally tick free.  What was the secret?  He told me a while ago but i cant recall (placement and grounding possibly).  Anyway, the resultant PCB is here, have a look in the build doc for the schematic and the PCB layout for placement.  Ive asked Erik for comment and will post here once he responds:

Sound Demo (note: no ticking ;) )

Eriks response:

1. Ground Plane (due the fact the zombie chorus needs a ground plane, vero may not be the best option for this project)

2. Made sure the Op-Amps were as far away from the CD4046 as possible, because the CD4046 releases a bit of electronic noise.

3. The resistors to the CD4046 for the R1 and R2 are very close to the CD4046 and are grounded to a ground plane. Those two resistors seem to be the "antennas" to a lot of the ticking.

4. Having a variable trim pot for the bias is extremely helpful. As is true from the old Boss CE-2, the MN3xxx BBD's are more sensitive to BIAS drifting than other chips, and so it needs more fine tuning.

(please share your own finds in this thread :D)

I know i might come across as a bit of a miser saying this but...i dont know...i see some things put out on the side of the road and think its just a huge waste.

I picked this up the other day.  I reckon it was used, maybe, a dozen times.  Gave it a bit of a clean and it came up great.  The tray is a bit dirty, but you know...its for powder coating...couldn't pass this up, i was considering buying a larger toaster oven just recently, but there is no way i would waste money on one, i see them thrown out on the side of the road ALL THE TIME.  Check out the size of this thing compared to my old toaster oven:

Thanks guys :D 2 weeks old today!

How did I not comment on this? Wonderful news! Congratulations.

Congrats Paul!

When we had our 2nd I was sure I'd never go to 3. Now we have 4. You never know what the future holds!


i kinda wish we had one more. But, my wife was already over 40 when we had #1. I'm hoping there will be a grandkid in about 15-20 years before I croak  ;)

Thanks mate.  Yes, over 40, this one has taken more of a toll (on my wife) then the first 2.  But...joseph is an AMAZING sleeper.  He's awake for maybe 1 or 2, 3 hour stint a day, but usually just falls asleep after his bottle.  He's like he's older brother who was the same.  Our 2nd, well, she was something totally different ... "the hooooorrroor...."

Joseph was born yesterday 2:00pm.  Mum and bub are doing well.  He's a cute little bugger, im sure thats just not parental bias? :)

I have turned off the store for a couple of days, if you need anything you can send me a message through the store and i will attend when i'm back on deck.

Cheers guys,
Paul (diygp)

Do you think we need a "Lets make pedals great again" thread?

Millennials aren’t interested in DIY for the most part, they’re a pretty disposable generation.

lol, what? You think it's all old farts who have been doing all the building in the last 10 years?

Or is this going to be one of those days where someone learns that millennials are almost 40 years old now? Birth years are 1980-1995, which I would guess accounts for a very large percentage of the people here.

I would agree with Jon on this one, if we are talking "millenials" by definition.  If we are referring to generation Z, well thats a whole different story and with a different theory. See extract from youtube analytics.  Sure, its youtube, but it still gives you an insight into what age group is searching for DIY pedal info

Note: 65+ and under 18 don't even register on the graph (0.2% and 0% respectively)

The moment you find out that complicated pedal your building isnt passing a signal.

No seriously, for me its creating something unique.  Sonically, physically, visually (youtube), pcb layouts, experimenting, finishing the enclosure etc etc. The reason for the enjoyment always comes back to the same thing.  Its a creative channel for me, like music and guitar.  It took me many years to realise this was the deep purpose of pedal building for me personally.

From a retail perceptive on the 'industry' i would actually disagree.  I cant talk about other stores, but I personally have never been busier.  Part of the reason im not on the forum as much these days, just trying to keep up with it all...

I agree, there are more pcb designers these days then 10 years ago, but i think thats more to do with the ease of fabrication and cheap cost to fabricate prototypes etc and accessibility more then anything.  Infact, it kind of confirms the hobby isnt slowing down.

Lastly, i recall seeing a thread on another forum, approximately 10 years ago, also announcing the end of the golden age (he used the same term).  But, we're still here :D

Just my 2 cents.

Well, that sucks John, your an asset to the community.  Glad to hear we will still see you around though. And you never know when that pedal itch might need scratching again? :) just kidding, all the best mate.

Wishing you the best mate, that sounds like a hard slog.  Its easy to underestimate the effect long term health problems have on your mental state.  How slowly it takes effect, so slow sometimes you dont even realise the dark tunnel you have been travelling down. But even if your condition is a lifelong journey, there must be ways to improve your situation.  There is always hope of improvement. Hoping things turn around buddy.
