Get yourself a used Herman Miller Aeron and call it a day. Where I live, there is generally a good selection of them on Craigslist for well under $300. I’ve tried a lot of other office/gaming chairs, and none of them have been as comfortable or good for my posture. They’re build very well, too...

Give the R.G. Keen method a try.

Those gains are great for fuzz pedals. I bought a hundred 2N1304 a while back and they had been great everywhere I used them.

Hola, esperamos que no seas un bot, jaja. ¿Qué tipo de circuito es tu proyecto?

You can also put your probe on the end of the resistor that connects to the collector of Q2.

That's been my thinking, too. (Admittedly, I also have mocked up a design for a consolidated I/O and relay bypass PCB, but that's kept me from pulling the trigger and ordering it.) Having separate boards for relay bypass also makes it easier when you're doing something like a Megalith or a Hoof...

I think that @szukalski may have made one like that, so it’s definitely doable

Q3's collector voltage is -9v?! 😲

Where do I sign up?

I’m game.

Do you try removing the 1044 and see if that stopped the whine? The NPN side doesn’t need the 1044.

Correct. You want to change the clipping caps (the ones between the diodes and the collector), not the coupling capacitors. I don’t have a standard order of making the changes, though.

Try 47n clipping caps, 430pF filter caps, and 1N400x/1N4150/KD521V clipping diodes. Adjust the transistor/collector resistors so that you get the collector voltage a little below half of VCC, e.g. 4.2-4.3v when VCC is 9v. Should get you some massive low end.

Germanium is much more temperature sensitive, so you can take advantage of that to figure out whether they are germanium or silicon. First, put the diode in the tester, and wait a minute for the heat of your fingers to dissipate and the diode to return to ambient temperature. Test the diode and...

Nice build! It’s one of my favorite fuzzes. Have you tried flipping Q2 (emitter to ground, collector to Mood)?
