Aaaahhhhhhhhh. I followed the schematic, not even considering that different transistors would have different pinouts. And I had the data sheet with that exact image staring me in the face the whole time. 🤦‍♂️

Yea, I like to have a more permanent solution, though, you know? And now I do.

excellent to know, thank you I've checked this a few times since you suggested it. The numbers jumped around a bit but seem to have settled at about 3-4 mV on the - side, about 4V on the + side. So pretty good! (I didn't notice that I was getting an mV measurement the first time and was very...

I used 2N3904s. I can't remember what research I did that lead me to that particular number as a replacement (probably this).

I was very careful about this but will definitely double check. So, basically an audio-probe-for-people-with-no-audio-probes. Very clever, not sure I ever would've thought of that. The points that you picked in your example: is there something special about them, or are they just easily...

Nope, but I've been meaning to DIY one with an old instrument cable — guess I've got my excuse to finally do it!

Hello! I've recently made my first breadboarding attempt (with the Uberfuzz — maybe a bit ambitious for a first time but I'm hoping to test a few component swaps). I've built it out, tested it, got zero signal, tore it out, and rebuilt it. Still no signal. I'm preeeeetty confident in the...

I haven't used it yet, but this seems like as good a place to start as any

Understood. As a thought experiment... Presumably there is a hunk of this circuit that's responsible for generating the octave effect. Looking at the schematic, the trimmer is located right with Q4 and Q5, so it seems like not too much of a stretch to assume that its something around there...

Touchy in what way? Subtle like phi1 said, or something else? Also yes, I plan on breadboarding it first to see how it all goes. Finally, the octave is less the point and more of a "sure, why not" thing. Otherwise we'd for sure be looking at more specialized effects.

Thanks, we'll keep that in mind! The subtlety makes sense. I know there's other things I could do to emphasize the octave effect — I think I read that omitting one of the transistors will? — but I'm not sure I'm at that level yet.

As soon as it's off waitlist, I'm going to be building an uberfuzz for my buddy. We were talking about potential mods and the idea of an external octave control pot came up. To my beginner mind, this mod is as simple as wiring a regular pot to the PCB in place of the trim pot, just a straight...

Well, thanks to you both! I'll confess I was a little skeptical about such a tiny thing making such a big difference, but it does.

Oooo, very interesting. I completely missed that part in the build doc. I do plan on adding an expression jack, just don't have it yet. Do you think that's part of the issue? Or just something you noticed and wanted to point out? Also when the expression jack does come, do you know what part...

Regarding transistor voltages, how do we know what to be looking for? Is it specific to transistor model (and therefore findable in product documents)? Determined by the circuit, somehow?

You don't even have to go all-out — in a pinch I've successfully enlarged a hole with a bottom-of-the-barrel bargain file. Plus they're handy to have around anyway.

Hi! Also new to the hobby, but I've had similar issues with a different build so I've picked up a tip or two. Or at least enough to help you get started. What's worked for me is just continuity testing the heck out of it. First start with the jacks — in bypass mode, touch one probe to the tip...

Hello, venerable forum! New builder, here — this is only my second non-kit build — and it looks like I've found myself a bit over my head. I have built a Leprechaun (Rainbow machine) clone and it works... ... ... kind of. With certain settings I can get a gentle vibrato sound, and with certain...
