Is there a way to check where the oscillation is comming from? I mean I started cutting the long input trace and wired the jack direktly to the input but unfortutelly that was not the issue :-)

The chalumeau of the guitar world. I made an attempt to make the pedal switchable without the fuzz. I was only partially successful. I may have to solder a pull-down resistor to the input, I think I read about it somewhere. Pin 1 and 8 of LM386 have been bent up/broken off and are connected via...

A picture but you cant really see something The parts all have the correct value. It is working except for the oscillation. The traces are ok. Some caps melted while I replaced some parts. LEDs missing. Maybe the layout in general is the problem.

Ok I forgot to add some files. It's not on strip board it's a produced pcb. Dumb as I am I use new circuits and put them in projects... The difference to the original version is that I hooked it to one supply with two other effects and added a 100n to each IC. My schematic is attached and this...

Hi everyone, I wanted to ask the collective intelligence in here to help me with a pedal. On FSB there is a new Baja Reactor V5 which I put in a combo pedal consisting of Reactor, Unicab and a Headphone amp. https://www.freestompboxes.org/viewtopic.php?p=300036#p300036 The reactor is causing...

I had this on areas where no solder tip touched the silk screen. Maybe the toothbrush wasn't that soft...

I did not do it for years then I tried it a few times with isopropyl alcohol 99,9% and a soft toothbrush but it turned out that I scratched the silkscreen somehow.... So I will not do it anymore :-)

Nice work! Do you use the chaos mode often? I skipped it in my Super Soda Meiser but added a drone knob which I never use :LOL:

This is what I want... Ikea Alex

If you got them cheap they are probably fakes. I bought a bag a few years ago and they were fake transistors. Cant bias them correctly. Source and drain should be interchangeable. Measure them Thread 'Half my J201s are bad?' https://forum.pedalpcb.com/threads/half-my-j201s-are-bad.18481/

Don’t waste money for a diy scopes. If you want to use it for other stuff than a pedal you will spend more money another one. To learn how it works it’s fine but fiddling around with the small controls is annoying. At least get a FNIRSI DPOX180H if you don’t want to use a pc with a pico scope...

Like this? Unfortunatelly discontinued. It was super cheap and not worth to copy. I paid 55€ on sale but regular it was not more than 100€ I think.

Thanks. I have to admint that it is not that perfect as the traces are not ideal in terms of crosstalk if that's correct. I can hear the ringer all the time when I use my headphone amplifier. Next time I can turn up the amp I will check there. Monetary concerns :-) I have multiple projects that...

Thanks a lot

Based on the fine BYOC schematics I built a Mu-Tron Octave Divider. The only thing that bothered me was the bass being low in volume. In this forum I found the R16/17 mod. Other than that the stock values are just fine (in my opinion). Because of the squeezed parts one knob is almost touching...

I stopped using a "project box" and "maybe later box" and all the single resistor bags. Finaly I found time to get some card protector sheets and put all the resistors in a ring binder. It's also nice for diodes. This is so relieving.... Caps are in 3d printed boxes. ICs, Transistors and all...

You could also put s piece of paper between the LED and the LDR. Xenotron hack:-)

You could copy the Moore Spark series. Unfortunately I cant find schematics or even gutshots...
