Yes this thing look amazing ! You speak and share it in another thread (thx 
) and i 've made dirrectly a stripboard layout
a future Kosmo format for me too 
For guitare i have a Metal Zone, a DS1, a Blues Driver and a Black Star with tube.
For the modular i use the Safety Valve, and i have also a Dual Distortion (from Niklas Rönneberg) more soft.
And use sometime some guitar pedals on the Stomp Box Adapter module.
and maybe soon make a Rat module and the Monotropa
For guitar I have only a DS-2 turbo, a π fuzz and a graphic eq in pedals for distortion or use my Marshall JMD:1
I have Made my Rat and it work!..
nearly.
it works and sounds awesome but my filter isn’t, its just another volume pot pre transistor kinda sounds cool but id rather a filter haha.
when I had it on breadboard it worked fine but in my translation to Protoboard it doesn’t seem to work (see attached layout). what am I doing wrong? what needs to be changed to get this to work?
Cheers for any contribution. [EDIT] green wire for top right pot is down a row I just messed up when making this
[Old design removed to avoid confusion]

I’d check those 2 caps and R1 in the bottom corner, it’s no obvious where those are in the stripboard. Infact I think that bottom section is the issue .
Also check the pin outout on the JFET as the 2N5458 is GSG 123 and you have the 1M hooked to pin 2 which is Source it should be Gate.
I got it all working!
I changed the JFET like you said I thought the pins where the same as the schematic, befits of being new to this but now the gain is much more appropriate. filter works too now I changed up the ground to be cleaner visually and apparently working better. Thanks heaps for the help!
I have attached the updated design by no means is it perfect but if it helps anyone with making their own that would be great
To avoid confusion I suggest you edit your earlier post to replace or remove the incorrect layout image.
Thx for that, I’m going to build this pedal soon, and after comparing the original schematic and your stripboard, I’m wondering if there’s a reason R7 went from 1.5K to 1K ?
there are also two D1 (it’s D2 & D3 attached to the switch)
so that the reading is simplified for those who would also like to build it, I would add that the pots are seen from below (+ indicate which is what Tone, Dist and Vol),
and also maybe indicate the polarity of the diodes / led (because without the diagram we can not know that they are connected reversed to each other)
for the rest “not verified”, title … can be a quick look here
the gnd of the Volume pot (bottom right) is not good, it must be connected one line lower on the stripboard.
and a question, I’m going to add a DPDT footswitch for a true bypass, but it only has 6 pins and I would like to add an indicator led when the fx is on
if I did as for a module I would do like this
is this a good way for a pedal ?
I’ve never seen the exact way you show and connected to the input but it seems kind of similar to the original rat bypass indicator.
It uses a darlington transistor with a pullup resistor.
I’m not sure about when it’s connected to the input bit this indicator can cause clicks when switching.

Here’s an interesting link. I’ve tried the millenium 2 bypass and it works fine.
I prefer 3pdt switches though
thanks, i’ll go look at this
Hey thanks for the feedback, this is my first time using this program.
Top right pot is distortion, left is the filter and bottom right is output attenuation.
the diodes are labeled wrong that’s my bad haha I got a bit ahead of myself due to excitement of it working. and the ground is wrong for the output again I was a bit exited haha however I fixed it all on the actual one I built.
as for the 1.5k turning into a 1k in the filter section I think during testing I changed it and preferred the sound? I can’t remember exactly it was a little while ago but it still works fine, Is it accurate? No but it is what it is I guess.
On the actual one I made I used a 3PDT and it does have a click when switching. Ill have to he a look at that resource, Thanks @konthaar043 and @Dud for the feedback I really appreciate it.
Maybe you could delete your old stripboard version which contains errors, and correct / complete it (title, source, …), before reposting it
plz for those who will use it to build it and after looking for hours where the problem comes from
Any love for the Gamechanger Audio Plasma Pedal?
Yeah, i can’t afford it either.
I could however afford this:
An aliexpress hv module and a surplus velleman xenon strobe tube.
If i power the tube with the hv module, it glows about the same as the tube in the plasma pedal.
If i connect my multimeter i measure about 250v dc over the flash tube, however it just barely glows with the meter connected
(Also not sure if my cheap multimeter is an accurate way to measure high frequency pulsed dc)
I’m thinking of audio modulating an 7805 to power the hv module, i hope i’m on the right track.
Does anyone know how it’s done in the real pedal?
Now that i’m thinking of it (still recovering from tonsillitis and fever)
I’m not sure where to take the output from in my circuit
