Ah, but it did work, you said. If it did, and it sounded good as you say, your circuit is okay, the fault is probably in a connection or a short. For me, those generally happen at the 3pdt or at the jacks. There is a bit of blobby soldering between the pots, there, but probably it's not the...

You need pics, my dude. Both sides, including the off-board wiring. Also in box. If it's working out of box, then most likely it's shorting on the enclosure, or there is a stray unwanted contact. You have pot dust covers?

After a recent "like" on this thread, just thought I would update. Never did get a reply. Dead letter. Oo. Good name for a pedal.

Diffuse is definitely a delay governing the gap between the initial signal and the onset of the reverberated signal similar to what goes on in the ghost echo. CCW= virtually no gap, CW = noticeable pause before reverb. And if you turn it and play, it gives a very nice evocative/...

To me, I love all the crazy little artifacts. Like what happens when you turn the diffuse knob while playing. I think the key knobs that really affect the pedal's behavior are in ascending order of importance, length (obvs), drag, and reflect. And mix. With mix at less than noon, you can...

But your off-board wiring stays oh-so fine... I also built this and I'll have to go check, but I think mine was a good ole 2n169 that won the covered germanium slot. I do like the pedal quite a bit, especially with the bass control cranked. Pretty excellent low and slow tones

You'd have better results in the troubleshooting forum I think. No ICs in this build. Could be useful to know what transistors you're using. You can measure voltages on the legs. The Wima cap on the left is also pretty badly melted, which could compromise the signal (haven't checked the...

Hahaha maybe too close to home

I think this might be relevant to more than a few people here: https://www.reddit.com/r/diypedals/s/TqhE6dEoiC

Just for posterity's sake, I found this pretty interesting page by Coda Effects. Don't know if Coda the user here is related or no, but... there it is. https://www.coda-effects.com/2015/11/big-muff-mods-and-tweaks.html

Oops--Yeah, that's what I meant, sorry. I was reading big muff circuit analysis while typing.

Since we have 4 dimensions of futzing here, do you all recommend a standard order of setting operations that can be productively employed before I dive in randomly? Like, set coupling caps>filter caps>transistor biasing>diodes?

Forgive the ignorance. By filter caps, you mean C2, 5, and 8 (the 470pf?) or the caps in the tone section (c10/11)?

Obviously I breadboarded to futz around with the circuit. For those who have futzed with muffs, particularly in the bass persuasion-- any recommendations to try? Right now I have 5088s in for Q1-4 and 1N4148s for the clippers.

Look what I made for the muffin board

Dudes, the Tremulus Lune/Trembling Loon builds are definitely the way to go. Pretty sure it's not harmonic, as I seem to remember a coming soon project that was supposed to be a tremulus lune controls-style harmonic trem. Pendulus Lune? Something like that.

Thank you much, folks. High praise from people who are actually making cool things happen in the circuit world, and notably @Erik S , whose impeccably immaculate wiring skills I can only hope to approach when I grow up.

Et voilà. This pedal kicks. I really liked the sound of the original name. "Animals" just resonated with me.

Well, it's done. I just can't level up past my amateur aesthetics. I guess I have to embrace the way of the blutac, because folks post some * popping * PTP pro circuits up on Reddit and are like, "yeah, second circuit ever. Easy, but could have done better." And I'm like Eff You, you (in...

Progress. I didn't bother doing my blow-by-blow this time. This time I decided to build the whole circuit and then tie it in. It's basically a copy of the schematic as it's been a while and I wasn't feeling particularly ambitious. Ground rail is to the right, 9v rail to the left. Major tie...
