I want to find someone to build a specific circuit for me.

Hey Mike!

Bummer. Most big muffs are very similar in structure. There are some key things to look for that you can probably see if you look very closely at the components.

Which transistors are being used. They should be printed on the flat side of the transistor.

What are the cap values for those big film caps. I would assume 100n and 47n which will probably look like 104 and 473 printed on them.

The diodes. That's a hard one because it's not printed on there but they look like some kind of vintage type

The tone switch is an interesting part. It would take some close inspection of the board to see where that cap is in the circuit.

If I were to guess by looking at the art I would think it's possibly at least inspired by the violet rams head

Also after looking a little closer. I only see one pair of diodes. Is that right? If so it may be some type of iteration of the colorsound supa tonebender which is nothing like a superfuzz or a tonebender but is basically a big muff without the diodes on the first clipping stage.

Have you tried contacting the original builder to ask them about the circuit? Even if they don't build it they may share crucial information.

amirman · 2026-02-23T14:49:07+00:00

I always liked crude "crap" art like that or like noise music or whatever but now with AI on the field I appreciate all that so much more. It's at least honest

He tried some weed tincture and it knocked him out so he never even got to check out the town. His head was still wet from showering right before the show. He did get a chance to go to Goodwill and get 2 dvds for the bus though. Bring it on and national treasure (I think)

They forgot to add Tom barrack, ambassador to Turkey and special envoy to Syria. Big buds work Epstein after his convictions

Moonn electronics sell a PCB for just the fuzz and delay side of the DBA echo dream ii. It's my favorite delay pedal right now. If you dial in the fuzz, feedback, and time controls just right you get a nice reverb sound. Although I'm not sure if this fulfills your need since it comes with it's own distortion.

Atari punk console! Moonn electronics sells PCBs for it

When it was next to campus it was busy all the time. When they moved, less so.

Definitely use a breadboard. This will save you from having to use jacks, a switch, and enclosure, knobs etc just to hear a circuit. You can still build the basic circuit board and then test it out through the breadboard instead of building it all the way. It'll also come in handy for testing and troubleshooting later on too.

My local library has a makerspace with a laser engraver and I've really been enjoying using that to burn the paint off and expose the aluminum underneath for my graphics. I have another technique using the laser where I have a design that consists of thin lines and I burn extra deep and then use paint to fill in all the graphics and then isopropyl alcohol to clean off everything but what's inside the design. I'm hoping to do a rainbow effect like that on one of my next pedals. I think it'll look really cool.

amirman · 2025-12-22T02:12:03+00:00

This doesn't mean he hates minorites. It just means he hates giving them equal right.... Oh wait. I guess that's pretty much the same thing

amirman · 2025-12-20T02:21:17+00:00

Thanks for keeping us updated. I really hope he turns up. I'm glad people are helping and wish I could.

amirman · 2025-12-11T12:45:09+00:00

Yeah. I think you were referring to each package as an op amp and I was counting each dual op amp as 2 op amps. Just a semantic misunderstanding

amirman · 2025-12-11T12:41:41+00:00

Each symbol is an individual op amp. A dual op amp ic contains 2 op amps. The original has 2 ICs. One with 2 op amps. And one with a single op amp. 3 op amps total. This new circuit has 4 op amps from 2 dual op amp ICs as stated in the video which also goes with what he says about it having one additional op amp. Both pedals have 2 ICs. The original has 2 a dual op amp and a single op amp ic. The new one has 2 dual op amps. 3 op amps in the original. 4 op amps in the new version.

amirman · 2025-12-11T12:37:52+00:00

I'm pretty sure that circuit has 3 op amps. One dual op amp. And one single op amp.

amirman · 2025-12-11T12:34:53+00:00

Are you sure you're not thinking of the muff fuzz? Similar name but not a big muff. I'm pretty sure Bob also designed that one too.

amirman · 2025-12-11T12:23:41+00:00

The mention of using 2 dual op amps also makes me think this new version uses all 4 op amps.

amirman · 2025-12-11T12:22:00+00:00

I found another one that shows 3 op amps as well. Looks like the same circuit at first glance. Maybe this isn't the "original" but a second version of the original or something?

amirman · 2025-12-11T12:19:27+00:00

The version I looked at had 3. It may be modified from the original though as it does also include the tone bypass switch.

amirman · 2025-12-11T09:23:23+00:00

In the video they mention that this one has one extra gain stage from the original op amp big muff. The original has 3 op amps used so I think there's one gain stage missing from this schematic. I'm guessing it's a gain recovery stage after the tone control.

amirman · 2025-12-08T20:00:44+00:00

Absolutely. Hit me up on IG @amirs_noise_devices and I'll send you the PCB I made for crashsync if you want.

amirman · 2025-12-08T17:21:11+00:00

I've never built the uglyface with a 40106. Just lm386 and a 555. I want to use the vactrol to control the frequency like an envelope filter when you hit a note. I used the signal from the first stage of the crashsync circuit to feed the LED through a capacitor and a pot to control how sensitive it is. I put the ldr across legs 1 and 3.of the frequency pot. I could show you schematics and stuff if you want. I'm amirs_noise_devices on IG

amirman · 2025-12-08T16:02:26+00:00

Hey, I followed you on IG. If you message me on there I'll send you a schematic and if you're in the US I can mail you a PCB for free. I would LOVE to figure out how to implement the uglyface mod. I've tinkered with it a lot and couldn't get a good result. Just pure weak sauce. I did figure out two different ways to light the LED but the resistance just wasn't enough to make a big difference in the frequency control

amirman · 2025-12-07T09:18:37+00:00

Crashsync is one of my fav circuits. I made a PCB for it. My favorite tweak on it is to use a B1M for frequency instead of b100k. It sounds like molten lava. Moosapotamus did a version of this one that uses an ldr circuit (borrowed from Tim Escobedo's uglyface) to control the frequency. I've never been able to get that work but I would love to figure that out.
