I’ll copy what I wrote in my IG post:

A couple of Big Muff pedals for the band. As a huge inspiration to me for decades and in essence a part of me, I just felt like doing something in return. These are headed out to SF today and I hope they enjoy them as much as I loved building them.

Salt Girl uses their take on the iconic Morton logo and swaps the text to “when it pains it roars” and is my take on it with the midhump tone switch to give it a bit more presence and most component values come from just experimenting with different combinations until I found what I feel a Muff should sound like. BC550s and 914s for clipping. I had the boards manufactured at OSHPark in Oregon using their clear solder mask on black. I absolutely love this look and stick the ground plane on the backside to show off the traces. I kept it pretty simple with the 4F logo and some lyrics from my favorite song on it. I chose these knobs as the white indicator line on them line up with the rain in the graphic when at 45° and don’t take away from the overall aesthetic. The clear lens turns a calm yellow when powered on and of course I had to use “Pain” on the Gain control.

The green one uses values from the Sovtek Green Russian Versions 7B and C- I used 2N5089 transistors here and 914s again. I used some EHX knobs and a red led and lens on a matte army green enclosure to complete the look. And the Cyrillic in the bottom left says “Made in Lafayette”. I dig it!

Here’s a quick demo, I’ll make a better one later.

Dude, both of these are awesome. From the PCB to the build, to the enclosure -- very nicely done.

EDIT: and the T-Shirt is very nice too.

Thanks! It’s a design they’ve been using since the 90s. They even asked for rights from Morton, which denied them, but they still use it.
