Yeah, that's what I found out experimenting with the pinning. It makes for a messy wiring, but at least, it works until I can get my hands on 2n5458s!

Guys, stop everything, I found the problem: it's the pinout on (our?) PF5102s that's not compatible with the way the PCBis laid out. I reversed pins 2 and 3 (source and gate, is it?) and it worked right away. I'll order some 5458s for the long term (as Stefanos suggested), and encourage you to...

I'm starting to sense a pattern here. I've written to Musikding, let's see what they answer.

That's kind of what I was wondering, too...

Oh I'm certainly not implying he is, but if they are fake indeed, it's best that he knows it as soon as possible, so he can fix the issue with the kits he's shipping for the short term and with his supplier for the long term.

Hi again everyone, I received new components today, and was able to build an audio probe. The results are pretty clear: the signal doesn't get past Q1. I have a crystal clear sound on my probe until leg 3 (and I do mean leg, not solder side of the socket), and nothing on leg 1 (which is normal...

Yeah, that'd be helpful. Who are your reference supppliers, usually? I haven't had to order single components yet (as opposed to ordering them as kits), but I may have too in the near future...

Here are the voltages I've measured on the IC pins, numbered as in the schematic attached. 1 : 9.1V 2: 4.6V 3: 4.2V 4: 0V 5: 0V 6: 4.6V 7: 9.1V 8: 9.1V I can't help but notice some differences between your measurements and mine; did you use the same pin order? Anyway, the symptoms you describe...

I have 8.8V and 0.3V for Q1 and 8.8V and 0.23V for Q5. So they are fine, right?

Great! Do I need to have some guitar signal going through the circuit, or is the power supply enough?

I do have one. How do I do that?

Will do, as well as reflow a couple of pots I was suggested, just to be sure. I'll wrap the LED leads in duct tape, just to be safe, but I don't think they were touching anything when I last tested the circuit. The two lower pots cannot touch the board, I've installed adhesive rubber pads on the...

Can you tell I don't have a clue about what I'm doing? :D Joke aside, you gotta admit that the naming conventions are less-than-crystal-clear for newbies like me...

Right, it's just the power supply for the status LED, I got excited over nothing... Unfortunately, I have zero spare parts available at hand; the only thing I could do is cannibalize a triplet of 2N5088s I have in another pedal. Here's a pic of the solder side, let me know if it's detailed enough.

Shit you're completely right! How could I have missed this when I have revied the wiring like a dozen times!? Thanks a lot!

I'll try both, just to be sure. I'll reflow the pots connexions tomorrow and order a couple ICs off amazon or something. If plan A doesn't work out, I'll wait for plan B to arrive in the mail. Worst case scenario is that I get a couple of spare ICs!

You mean add solder and make sure the connection is properly made for each lug?

That's interesting. Is there anyway to tell if the 308 I have is fake?

It's a pair of PF5102, I got everything as a kit from musikding.de.

Hi everyone, I've contemplated building pedals for a long time, but took the plunge only a few weeks ago. My first two (simple) builds went smoothly, but I ran into my first non-working build yesterday with a Parentheses Mini Fuzz, that is in fact half-working. The bypassed signal is normal...
