Which two muff variants would you build on it?

 

[thomasbe86]

all at max, triangle in pink, ram's head in green, civil war in blue, green russian in orange.
I'd go for ram's head and triangle just because I have never built any

I built a Triangle / Mascis (and I believe that's a Rams Head) variant to test the PCB, just because the values looked different enough to not be subtle.

It was not subtle.

The Mascis sounds neutered compared to the low end of the triangle.

Is it possible to swap the toggle to have parallel muffs? I would maybe split the tone control if I did that.

 

[Robert]

Yeah I was planning to pull out the toggle to try running them in parallel with a single blend control.

Since you mentioned splitting the tone control, it'd actually be cool to split all three controls.... Then you could mix with the volume controls as well.

This is going to turn into 2 blendable Muffin Factory circuits with a series/parallel switch....

Just saying....

Oh nice!

Shouldn’t be too hard to rework the board to be a stereo muff if you ditch the toggle switch and rework the I/O pads. All I’m saying is a stereo muff could be preeeeety cool for totally fvcking up stereo synths and stuff

As someone who recently found the 8 VARIATIONS listed in the Muffin Fuzz build doc and was contemplating ordering 7 more Muffin PCB's, I REALLY like this new PCB. I feel like I'll be ordering 4 and then technically owning 2 Green Russian clones...

 

[Bricksnbeatles]

Oh also, @Robert do you think you could make a board that switches between Op-Amp and Transistor Muff? I’m suddenly hankering to make one that can switch between V4/V5 op amp specs and Guild Foxey Lady specs so I can have Belew & Fripp in the same box.

Looks like this board is already a tight fit, but idk, maybe SMD op amps or 1/8w resistors if the footprint would otherwise be too large for a 125B

 

[Robert]

Yes, it's a little more difficult, but it should be possible.

Next, deucetones and twob screamers

Double muffin arrived today but no components silkscreened on the board. Same with Oroideous Drive. When you have a chance, please post BOMs. Have a great holiday and thanks for all you do! New projects lately have been awesome

I’d bet anything it’ll be the same ref des as the standard Muffin Fuzz

 

[Robert]

Yep, BOMs are identical to the Muffin, just pick two variants and populate each side.

A = Toggle Down
B = Toggle Up

3 x B100K Dual Gang pots
1 x DPDT ON/ON toggle

I'll try to get the doc posted later today.
