Big Muff vero - different variants

I'm not sure did I ever post it, I guess I'm not... So here it is.
Layouts for several Big Muff variants, and as a cherry on top Jordan Creator Model 6000, which is basically twicked Muff Clone. Sounds very marshall-ish. Could be good start for your kind-off Cornish build. I won't be surprised at all if Cornish SS-3 is extended version of this, REALLY
Anyway, as I said number of times bigger is better? Not this time, those vero layouts are the smallest I've seen. Some component raster may be odd to some of you, but I draw it with my components in mind, those components I had in hand, bigass ceramics, and such. You can get away with common component raster just removing some jumpers. Most of those layouts can be build with standard IC friendly 0,1" vero, but I like it with 0,15". You'll have a problem building Triangle version on 0,1" as it was minded with small axial e-caps mounted vertically - BC Components, 25V are cute here
But... Creativity is your friend, this is why vero is so cool, go wild, I'm sure you'll be fine
This time verified (some of them)
Mostly based on Kit Rae awesome schematic, but not all of them. As a bonus duomuff (two muffs in one box with master bypass and circuit A/B shift)

Sweet Jesus Sinner! Thanks! Now i have to figure out a way to get all of these things in one enclosure for a REALLY big muff.

great idea

...and my pleasure

Good Lord ! It's every Muff ever !
Thank you so much for sharing this, it must have taken some time to put this together.

What kind of diodes does the Jordan use? Do you have a schematic for it?

It uses 1N4001 Silicon rectifiers.
Here's mine.

Thanks Kit, special thanks for your schematics.
Feel free to use any of my layouts at your website if you like them

The transistors are drawn wrongly - they should be NPN or they're not 2N5088 equivalents.
Incidentally, my Jordan Creator has a 12k collector resistor for the final stage and for the first clipper stage, uses some weird Fairchild transistor (each one has an hfe of ~250), and has negative ground.

Yeah, I need to clarify that whenever I get this on the website. Clones should be made NPN with 2N5088's. The SPS 3353 was apparently a house number. Whatever those original transistor part numbers were is unknown, but I suspect it was a 2N5133 equivalent, or even a 2N5133, if Motorola was making the same spec trany back then. EHX did the same thing with the Fairchild 2N5133's marked with the FS36999 house number. Both right around 1971 incidentally.
Mine are PNP, but the transistors have the same number. I know of two other Creators with the same tranys, but they are NPN. I saw a Motorola list with NPN 2N5088 as a modern equivalent for the SPS 3353, making mine the oddball. I think that list was dug up by Chris Mahoney when he made his clone.
I have seen 12k collector resistors in two other Creators, and two others with 500pF filter/feedback caps rather than 560 in the second and third stages. Seems Jordan was not only cloning, but taking lessons on consistency from EHX...or it could have just been a running change.

Not to step on any toes with Pawel's great layouts above, but I wanted to make a generic layout where the part numbers matched those that Kit uses in the schematics on his site. That way one could keep the same layout and have a whole list of different variants and could get an at-a-glance look at the differences. Here's what i've got so far:
Its certainly not an efficient use of space, but I personally like laying my resistors down. Anyway...thought i should post it here for completeness. Unverified as of right now, but ive checked it on screen and it looks right.

Wow! Great job!

Good work doc!
When I look on mines I think I should revise them, component spacing is silly (in mine), I chosen that parts raster for components I had on hand
Anyway, great job bro

Thank you, Dr. Balls ! Some great additions.
what schematic matches with the part numbers in your Excel sheet,
this one from Kit's page ?

Yep! All of his schematics are labeled with the same part names, so just sub in whatever values are needed for a specific version, or mix and match! The layout still hasnt been verified, though, so let me know if you try it!

Here's an updated and verified version of my layout:

Nice work. I think you are missing one of the Triangles, and four of the Ram's Heads BMP's I have on the website, if you want to make this more complete.
I am up to 12 V1 schematic variants, 17 V2 variants, and 7 V3's. All of them were likely made in long runs of hundreds to thousands, some much more common that others. I don't think there is any circuit that I have not seen multiple examples of now, but I know there are probably a few I have never seen. I'm definitely not going to post all of them, but I may do a similar chart to yours that tracks the major circuit changes. The audible differences are very minor between most of these, so I'm trying to just post the ones that sound different enough to me to be worthwhile.

Ooops, actually there are 8 V3's now. I just saw a partial photo of Frank Zappas V3 circuit a few weeks ago, and naturally it is a weird set of component values that I have never seen before!
