Is this a solder bridge I see before me? middle-left lane, under the A10k pot.

According to the GGG schematic, it's 100n. If you go to the other thread, feral feline did a solid and outlined the changes from a green Russian. There are a couple other changes as well.

Yep, there's a whole discussion Here. Still in breadboard form for me as I still have to retest and try some stuff.

That is super weird. I've never had that experience, and I'm not sure IPA would be the culprit since it evaporates within a couple of seconds. In future, the best thing to do after a thorough visual inspection and component check is probably an audio probe--you can find out where the gating...

Dang it! I was just about to post about the Marshall pedals. Many demos.

Looks like your TL074 is in the wrong way. If there's only a dot, use the dot (pin 1) to orient ICs; if there's a notch, the notch takes priority. The sockets are agnostic to the plastic they're encased in, it's the pin connection that matters. I use 32-pin in-line snappable sockets.

I think there is currently questing around this.

I really like this. 1 main stereo mic input and 4 open XLR/ts inputs, expandable to 6. So, it's kind of like a very portable 4-6 track recorder/mixer. I bought it for field recordings and sound collage. The 32 bit float allows recording very quiet sounds and quite loud sounds without needing...

There is a list of Marshall in a box circuits somewhere here--might be a good starting point. Now, particularly for the verisimilitude of a Plexi voicing, I don't know, but the Colombo Plexi Breed/Golden Falk is pretty darn good. Subdecay Variac OD also

Well shucks and consarnit. Was looking to implement the Pyrocumulus tone stack and realized I'd done made breadboard errors. Breadboard ferkakte because I neglected to put in C11 (10 nf to ground off tone pot) and instead stuck the 10nf in C12, which was supposed to be 100nf. Rectified it...

True, although it's worth mentioning for the record that the Sunnbeam and Sasquatch are Effects Layouts boards, and the Apostle is a GCI board. I think the Sunnbeam error is on the pcb print and is noted in the build docs [edit: as you mentioned--need more coffee]. The Apostle, as far as I...

Actually, if you read around, I think one being a bit wimpier than the other is par for the course. Is on mine. Is this what you're seeing?

[OH, DAMMIT! This is for a circuit without c11 and c12 at 10nf, see below.] I guess this could go in build reports or mods, but I'll just continue here. The stock bluebeard (with 220uf-100uf power cap as the only mod) is solid. I'm not sure exactly why folks see it as the bass ne plus ultra...

Here is the schematic, by the way.

I concur with @falco_femoralis. I had actually typed "diode situation suggests a ground fault." What about C3, though? Isn't that the cap you kludged up? Could be an incomplete solder/solder crack or second component leg going awry. Kludgery usually involves a greater danger of...

Sounds like the issue is in or around the 1st half of the IC, since you have signal going into 3--off of R9? Couldn't see if R9 is 100k, btw. You can also try jumpering between connections to see if a trace is dead. What's puzzling is that apparently it worked. What would stop the signal at...

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.
