So this might be my last build report for a while.

We have Hurricane Ian coming right over my house as a Category 1 as of the last update sometime Thursday.
We should be feeling the effects starting tomorrow afternoon as the feeder bands start creeping into Central Florida.

Cat 1 is not a big deal for us Floridians. More of an annoyance than anything else. But I will probably be losing power, internet and cell for a bit.

I knew I should have invested in a butane soldering iron :ROFLMAO: .

That and a "Mustang Headphone Amp" hahah. Well, might be time to break out the ukulele and acoustics!

Anyway, I spent most of the day doing storm prep. Got my generators out of storage, blocks of ice frozen and helped out a couple of neighbors get ready. Since I took the day off, I decided to try to get one last build in before the storm hits. I needed something fairly easy and fast so I decided to build the Muffin Fuzz board I got in my last haul from PedalPCB.com.

I've built I think 4 or 5 fuzzes now and starting to get a sense of very wide range of tones available. One thing glaringly missing in my fuzz-education was a Bg Muff. When I started looking over the build docs to prepare for the build I was faced with option overload with all the variants I could build with this board. So I consulted with the resident fuzzolgists @Big Monk and @Coda.

After chatting with them a bit I decided to start with building the Triangle variant. I have a feeling I probably need to order a few more of these and build some of the other variants.

I had recently scored some vintage Telefunken BC239C's from Electronic Goldmine. They all measured between the low 200's and low 400's in gains. Based on @Big Monk's guidance I chose 4 of the lower gain ones to use. I also followed his advice to use linear pots for all the controls.

Other than that, some substitutions I needed were the 4nf cap (used a 3.9n that measured on the high side). The 50nf caps I used 47n's that measured a bit on the high side.

Build went super smooth and fast and when I fired it up I was like WOW. This thing is pretty awesome! Loud as heck too!
It was exactly as @Coda described it would be.

"lots of sustain, singing, sweet highs, big ol' fat low end, with a little bit of crispiness to provide definition..."

That about nails it. It's definitely different from the Fuzz Face variants I've built. It might be my favorite fuzz yet. There's a whole lotta Fripp and Gilmour in this box to explore! Thanks for the guidance @Coda and @Big Monk. Now I gotta order a few more boards.....hahah.

I got these orange enclosures to build the XC Phase before realizing it wouldn't fit. I have one more I'm saving for my Dist+ build when I get to it. Looks very much like I remember the old MXR boxes color. But not the Big Muff Pi I played when I was kid. Although I think I've seen EHX release an orange one at some point. But this is MY Triangle Muff....and it's orange....so......

I was actually a little confused by the silkscreen layout with the option of e-caps. I assume that some of the other variants call for e-caps? The values seemed more "film cap-ish" so that's what I went with hahah.

You are all good. Here is my Green Muff build. All film as well and sounds exactly like the real one I bought as a teen in the 90s.

I think 1u film box caps might be a tight fit so Bugg made those slots electros. Plus there are some of the original circuits with 1u electros so....
 
The NYC EHX uses 1uF electrolytics, the solid state portion of the "Bigger Muff" used 10uF, there's at least one other variant that had a couple 10uF scattered around.


For film caps use the outer two pads.

For electrolytics use the positive and center pad.
 
What do all these variants refer to? I know the "Ram's Head" has a Rams Head on the enclosure....but what about the rest of them? "Civilian"?
 
Civilian - Civil War
Double-G - G2 (although I'd recommend the Germanium II project for that)
Martian Fuzz - Dead Astronaut Space Fuzz (one particular setting)
Bigger Muffin - Solid-state portion of the Bigger Muff
Stomp 75 - SUF 75 Rams Head
Mask Us - SUF 76 Rams Head (J Mascis / Dinosaur Jr)
The Fox - Foxx Tone Machine

Ok I didn't realize those were "pun laden" names....I was taking them seriously...hahah

I think that's the next one for me, the Green Russian. I've heard so much about it but never played one.
I've built lots of Muffs over the years but never did a Green variant until just last week. I always thought they were all pretty close but the Green Russian surprised me. A bit more grit than the other variants. I highly recommend it. I also recommend the Dream Fuzz and Cream Pie for over the top saturated sustain. Stay safe!!!
