Every single FET circuit I've ever played with has sounded a million times better at 18-24v.

Do you have a pedal with buffered bypass? Put it in the front of the chain with everything off and see if it makes a difference.

You can use any kind of capacitor your want there. Electrolytics are cheap, and in that position they're out of the audio path so no need for anything super fancy. There's not even much DC derating of caps to worry about. Most people would prefer to work with THT electros over a SMD MLCCs

Updates, and an ETA on I/O boards?

Trimpots turned up for the Trueman. Got it working then bit the bullet - removed the original bias knob, conventionally biased both stages, and fitted a fuzz control with only one trace cut/one resistor removed. Sounds even better than the original and totally reversible - other people I've seen...

There are no parts being hoarded by anybody that is making them hard to find for builders. It's a you problem my friend

G'day, Bought a couple of cheap grab bags of germaniums out of Eastern Europe from eBay, and was expecting a reasonable rate of failure due to leakage/poor gain - and to my shock, there was only a single bad transistor! I've got: *half a dozen GT402B's (100-150hfe, <150uA of leakage) *handful...

Not sure how much this will help, but I've attached drawings of all the parts for a Boss wah - the top plate sits inside the recess for the rubber tread, the smaller end plate sits in the recess for the name badge, and the bottom plate covers the entire base. Top/end plates have a couple of...

Schematic I posted is right, I just forgot to change the value on the emitter cap after adding it. Changing the 1k resistor to a pot is the modification I am going to do to make the fuzz infinitely more useful.

I had already removed the trim pots ages ago to trace - the second measured under 1k, and the 200k was open. I'm going to guess that could have been a problem 😅

So, it's a single sided board. On the transistor itself, the collector is tied to the case. The collector pads are connected to the plating around the hole for the transistor lip AND the two pads for the soldered wire-tie around the transistors - but none of these have any contact with the case...

Done

You are, but that would be a much better take on it. It's basically just a germanium, positive ground One Knob Fuzz with a voicing switch to change between collector values/coupling caps on the second transistor. The bias control appears to be on the collector of the first transistor, but there...

Picked it up for cheap as it doesn't work, and trying to figure out what's going on. There's some....real jank here for a shockingly well made pedal. I've got the bones of it figured out, but the multiple trimpots (where the issues lie) are throwing me for a loop

Done!

Yo dawg, I heard you like buffers.

I've been working on a little wave shaper that's an amalgamation of Escobedo's SSWSMS and precision rectifier (that you can dial in between half and full wave rectified) Taken a little bit of work including finding out I had a dodgy batch of diodes AND a dead op-amp, and something real weird...

Ok bizarre - some quirk with zone transparency that I solved by opening the file on another machine, saving it, then going back to the original machine. Fixed now!

I don't want it for editing my silkscreen. I like having a good idea of where everything is and where it's going so I can visualise the PCB better. Every other version of Kicad has had this by default. It's on. The silkscreen is hidden underneath the copper layers - if I turn f/b copper off I...

I feel like I am going crazy here. I've used Kicad 5 through 9, and a lot of the PCB editor changes have been particularly frustrating. My newest problem is that no matter what I do, my silkscreen layers disappear under any copper layers making it very hard to see what's going on. PCB created...
