David Gilmour used the Sovtek Civil War Big Muff in the Pulse Tour in combination with the B.K. Tube Overdrive to créate a new distortion sound that still uses in recent records.

A photo of Thurston Moore's pedalboard shows he uses a Sovtek Civil War Big Muff distortion pedal (this photo's time period is undetermined).

In this early photo of Sleep, Matt is playing a Civil War Big Muff.

Gerard Way mentions on Instagram that he recently purchased the Electro-Harmonix Sovtek "Civil War" Big Muff Pi V7/V7A, a pedal he had long desired. He notes its use during the recording of "S/C/A/R/E/C/R/O/W" on the album "Danger Days" with producer Rob Cavallo's unit.

"John is a Russian Big Muff collector and has used them from time to time.

'That is a Russian, Civil War era Big Muff pedal making that noise in the middle (of Mystic Highway). A lot of people don’t know what I am talking about. I have quite a collection of Russian Big Muffs. They are very unique and I wanted to use that to add to that hippie vibe.' - John Fogerty in 2013"

A desert island backline for me would be a Travis Bean Standard koa model along with a [Sunn] model T full stack. I could even do a half stack for a small club or beach hut. I would also choose a Les Paul with P-90s and go with the model T. I would take a RAT too, but I would need to bring along an EHX Sovtek Civil War Big Muff as well.

At the 48:09 mark in the YouTube video titled "Sunday Live Chat: a look back THE PROCESS! 10/15/23" by SCAREMEISTER, a brief glimpse reveals the Electro-Harmonix Sovtek "Civil War" Big Muff Pi V7/V7A pedal in the bottom right of the frame, confirming its use in Skinny Puppy's 1996 setup by cEvin Key.

It seems today that all we see, is violence in movies and sex on tv

Pedal 89 in Stompbox: 100 Pedals of the World's Greatest Guitarists, as can be seen in the quick browse video at 0:37. It was sold to Blackbook Guitars in 2015, who reached out to Stomp Under Foot for a limited edition clone: the Fuzz Honey. The original seems to have been re-aqcuired by the time Stompbox was being made, however. The Fuzz Honey's product description is archived on Effects Database's page for it.

I am really happy to announce an exclusive pedal for Blackbook Guitars in Portland, Oregon.

The owner of Blackbook, Nate, contacted me about making a copy of Mudhoney’s, Steve Turner’s, original Civil War Big Muff that was used on all the early Mudhoney albums.

Being very familiar with the Civil War, as I have been making them for over six years now, and a fan of Mudhoney, I was very excited about this project.

Steve personally sold the pedal to Blackbook and has even commented on it through his Instagram page.

The pedal is called the Fuzz Honey and, as with all the Stomp Under Foot pedals, these are handmade in the USA.

The Fuzz Honey also uses original, NOS, Russian transistors and the same exact resistors and capacitors like the original.

These are limited to thirty pedals.

Mentioned in this December 10, 2020 Guitar interview and deducible given Nevermind’s 1991 release year.

“And we only used a couple of pedals. Kurt had a Big Muff. And I think I had a Russian Big Muff, which is, you know, very close. And he had a RAT. And then he had a Small Clone, which is sort of the watery effect on Teen Spirit in the verses. Come As You Are as well. But that was it; a pretty simple setup, really.
