It looks like only one of your jacks has a ground wire to the board, if I'm seeing correctly. You would need both if you're testing outside the box. Hope you can get it working! I built this year's ago and it's great.

Cult of Germanium, sign me up already! Now I want to know more about the circuit so will check out Chuck's writeup. Looks like your build uses NPN germanium? Is the vero available?

Hmm, looks like I have one of those Ge lm1458s in my stash! All kidding aside, EHX did do that a lot, so who knows. Also, I had totally forgotten Brett Kingman exists...

Anyone know what the story is with the germanium version that the maker of the original put out a while back?

I had an old no-led Rat 2 back in the early 90s. I sold it at some point when I thought the filter knob was no longer working. Kicking myself years later as it would have been an easy fix! Would be curious to see the innards of a recent one too.

Forgot to mention, the optical bypass does use the H11F1M. Still like that design a lot and it's never given me issues.

Thank you! I took a look at Jason's Ubu Roi schem and could see the difference right away, very similar to what you mentioned as the moreideal configuration. He's got me covered but I'll probably try this fix at some point for fun and to potentially sell the GOAT off.

I would not have guessed there is anything fundamentally off with the design! Will DM you shortly...

I did a BB-type build recently and am getting some intermittent footswitch pop, even though I used an opto bypass that should prevent that. Checking for voltage at the circuit in and out, I see that there is voltage on the output going from 0v up to just over 1mv. It sort of builds up slowly and...

Nice! All but one of my TB builds have just been wired as positive ground but of course are battery-only. Did not know there was a way to daisy chain without a charge pump. I did a PNP Fuzz Face recently and I'm pretty sure the charge pump is introducing noise and even causing some odd behavior...

That was a dual-channel preamp using FETs and Ge diodes. The FET needed for it went extinct so it was a short-lived offering. You could probably still find posts about it on the Madbean forum from around 2016-17. I know it probably inspired some of jubal81's offerings as Bolt and Forge.

Thank you! I realized I am getting some intermittent footswitch pop on this even though I used an opto-bypass setup, lol...I'm suspecting a dodgy electro leaking DC, but can live with it until I get a chance to swap 'em out.

This is a modded Bluesbreaker-type board that jubal81 gave me years ago. I've not had much motivation to build overdrives since his Cascadia is so awesome, but I was having some nostalgia for the now-defunct Grind Customs when digging through my PCB stash, and I also hadn't really tried anything...

Nice! This is on my eventual build list too. I've done a Standard Fuzz and a Kay Fuzz with a bunch of mods Mark Hammer came up with. They're both great but I have to do them all...that's a helpful point about the noise floor.

Great build! I think I remember seeing that this circuit has some resemblance to the Keeley Fuzz Head, which I've build more than once and like a lot. I would like to go to Australia again as well. Can't move for the amazing bird life! Those shifty Ibis do like to come try and steal your food in...
