That may not be enough. You may need some extra buffering either on send or return or both.

I hosted a pedal making workshop twice in a makerspace in Brooklyn a few years ago. It was fun and I think people liked it. I basically guided them through building a pedal (the Amentum). The space didn’t have great irons or equipment so getting good solder joints was hard and debugging was...

It’s been so long since I came up with the graphics idea that I forgot to explain: the colors are not random, they represent the spectrum of solar radiation. You know, to stay with the theme of the original. And Helios of course is the Greek god of the sun.

Alright, it seems like I am getting back into a groove building pedals. This is my second one this year and the 5th in about 6 months, which is a record for me after years of not building much of anything. Last famous words, I will post another build report in 2028 lol. I procrastinated...

Just finished my Sandspur and found this thread. Thank you @jjjimi84! I think this pedal sounds pretty good. But I am getting some weird artifacts if the fuzz knob is all the way up. If I pull back a smidge, the artifacts go away. These sound like a mix between a weird gating sound and space...

OMG I should teach my kids to solder! Very nice looking build!

Is it doable to put a decal on an enclosure that was already drilled? I have a bunch of them for projects in my backlog (I box all of them) and they would be perfect to try this with.

I bought a sheet of sunnyscopa a few years ago and never used it because honestly I was intimidated. But this tutorial makes it sound not too hard. I already have an old toaster oven in the basement…

The adafruit stuff is really good. I built one of their kits and it was very fun and easy to program. Their stuff can use the Arduino IDE but they also have a Python version which is even easier to use (but performance is not as good of course).

I would sand around jacks, pots and switches. Power plugs are usually isolated. If the noise issue doesn’t improve I would consider starting a troubleshooting thread.

I haven’t seen a lot of build reports for this little guy, which is a shame! Such a fun and useful little tool to build. Highly recommended! This was my first (mostly) SMD build and the smallest enclosure I have worked with. Also the first time I used a custom drill template with Tayda (the...

I can’t wait to try this out. I use Inkscape and was never able to make it work for Tayda UV and I never bought AD to use it instead, mostly because I could never find the time to do it. Thank you for sharing!

Thanks! I’ll probe around those. I hope I don’t have to desolder the SMD…

Alright, I did not have time to open the pedal up for more beauty shots, but I did record a short demo to exemplify the problem. You can hopefully hear the pedal clicking and the increased noise floor. Then I noodled with the pedal on, then turned the mix all the way down towards the end to show...

I forgot to mention that the noise is there even when the mix is at 0 and doesn’t change at all with mix. So I suspect there is something producing it in the clean path. I don’t think I get any BBD or oscillator noise at all.

I couldn’t verify whether it is actually symmetrical so if you have it oriented backwards it may be good to try flipping it. But it may not solve your issue.

The pinout for the 2SK117 looks the same in those two sources to me. Drain is leftmost looking at it from the flat side. Besides, FET’s drain and source are usually interchangeable.

That’s the only picture I have. I can take more tomorrow.

Hey guys, I recently finished this build and I really like the pedal, but the noise floor seems unusually high. As soon as I turn the pedal on, white noise is very audible. I’m using a CS7 which has been working fine for years. I’m wondering if I might have a bad cap or if I didn’t adjust the...

From the perspective of the signal (not DC), ground, Vref, Vcc and -Vcc are all equivalent because they are all ground for AC.
