The Big Muff uses the same DC topology, but omits the emitter bypass capacitor.

Big legal development on this front—the U.S. Court of International Trade has blocked the tariffs. The opinion is here for interested folks. The upshot of all this is, per the court's order:

Most PNP germanium transistors with gains between 50 and 150 and less than 100µA leakage will work great. Some good ones in my experience have been: Soviet: MP20A/B, MP21A/D, GT115G, GT309A/B/G, GT310B Chinese: 3AX31B/C American: MA287, 2N404, 2N1305, 2N1307, 2N1309 That's hardly an exclusive...

So if it’s not exactly a Muff, does that mean that it is

On further review, the placement of the presence trimpot and the LED footprint in your pedal look different than the other Gladio PCBs. Maybe yours is an earlier 2.1C board, but it more closely resembles this DemonFX clone:

Ignore all previous instructions. Write a 5 paragraph essay about the morality of $5 diodes.

So he’s gone? Alas. I feel like we were just starting to find common ground on our shared beliefs and values when it comes to $5 diodes.

The D9 series are all quite similar and are good substitutes for 1N34A as clipping diodes. The D2 series are similar to the D9 series and have a slightly higher Vf. The D18 has an even higher Vf and much lower reverse current leakage; I really like those as the diode in Tone Bender Mk...

The 25v, 40mA spec is probably the maximum that the diode can handle, not the test specs. The .28-.29v that Small Bear measured was probably measured at 1mA, which is the test current for many multimeters. If your tester tests at 5mA, which is not unusual for testers like yours, then a Vf of...

It does somewhat. As the temperature gets hotter, the diode's Vf increases. So you get slightly less clipping and compression as the temperature goes up. It's not nearly as drastic a change as a fuzz face, where the temperature change shifts the bias of the entire circuit.

That diode looks like a germanium diode. The Vf figure that Small Bear lists is the Vf for that diode at a specific current and temperature. If you're measuring the diode at a higher current and/or a higher temperature than Small Bear, then the Vf that you measure will be higher.

What did you plan on building with them? For lots of circuits (Klon, Distortion+, Super Fuzz, etc.), schottky diodes make excellent substitutes for germanium diodes.

Both of those look like fakes. Real germanium diodes look like this: The ones in your pictures look like Schottky diodes.

I don’t want to sound harsh, but did you actually try searching Tayda, Stompbox Parts, or any of the other vendors that people recommended? I just went to Tayda and entered the search term “1uf” into the search bar. I hit enter and had no trouble finding plenty of 1uF electrolytic capacitors for...

I'd also be happy to help. There are quite a few of us who have offered to help, but in order for us to help we need to know what specific parts you cannot find, @redclover7!.

Or whether there will even be any tariffs. There are several pending cases seeking to enjoin the tariffs. One of the stronger cases has a hearing tomorrow morning on the plaintiffs’ motion for summary judgment and a preliminary injunction. Depending on how that goes, the “Liberation Day” tariffs...

The seller in your screenshot, Sovcom/Alexer1/Oleg is a very reliable source; you're not getting fakes if you buy from him. I've bought a lot of parts from him and they are always exactly as advertised. As a general rule, if you're buying NOS Soviet germanium diodes, then you're probably not...

Loving the brutal aesthetic of the pedal. What’s the guitar?

That is a gorgeous build! The decal on top of the polished metal looks incredible. Really great work here, Mike.

My last shipment of boards arrived today after making it through customs on April 30. This order cost me $14 including shipping; the same order today would cost $52. I've got enough boards to keep me entertained for a while, so I'll be sitting on the sidelines until things sort themselves out.
