I am looking for help adding a Treble and Bass control to the Fat Boost circuit to get into the v2/v3 type of circuit. Ive messed around with a couple ideas without much luck. This is obviously a very simple circuit and adding T and B instead of a single tone control shouldn’t be difficult. Maybe so...

Toneman, I too am familiar with google. I was specifically looking for the Gaussmarkov pcb and bom. I came here because I was unable to find them through google searches. I appreciate your effort, but it was not helpful. I will try the waybackmachine.

Does anyone have the pcb and bom from the Gaussmarkov Gristleizer project? I have a couple of old pcbs and the old website is no more. I am hoping someone has the project files saved and can post them or message me. Thanks

Where are we at with the cap values? I will build one from the last vero once those are posted.

The layout is no good. DOuble check it.

Do I detect some sass?

The delay itself is fairly noisey. I've found this to be true on the actual pedal and the vero. I haven't had any lfo ticking issues like you are having on either.

It is now verified and working. I mistakenly ran a ground wire from the pots to the second to last row on the left and that made my LFO not work. TOok that out and now its good to go.

Can you double check the lfo section. I made the vero layout and have built it and only the delay is working right now. Im triple checking my layout to your schematic and I'm not seeing any problems. The LED is on but not fluctuating at all.

Unverified but I will be building it today. You could make those middle bottom wires into links and add 2 rows on the bottom if you need all of your wires to be on the sides.

Looking back, I would have done all of the phase stages off of one tl074, but I digress. I used NSL32's in my build which are the modern equivalent of...

It works and sounds awesome.

Whats up with the trimpot underneath?

Sounds awesome. What might you expert circuit analysts call this a variation of? A bastard Tonebender?

I built it from the schematic and Ive found the tone pot doesnt have much range. Anyone else find anything similar? It does sound nice though.

This pedal is the shit. I love the sweep of the EQ. Extreme to extreme. Sounds Awesome.

You need a cut at E9 then its verified.

I just built Derringer's layout and it sounds fantastic. I love the Tone pot vs the switch. This one's gettin on the board right behind my megalith clone.

Does the circuit have to have a cmos quad opamp or can I use a tl074? Only one of the 4 opamps are used and the LM660cn is pretty hard to source.

I took the vactrol out and messed around with the led/ldr and Im happy with it now. Id call that layout verified but it looks like it could be shaved down a bit. Maybe I'll have a crack at it and post my layout this weekend.
