Open Discussion / Re: KiCad 3PDT schematic symbol.....?
« on: May 17, 2022, 01:09:06 PM »
Thanks for this. I'll take a look at it. I used the Sparkfun symbols with the three footprints and just deleted two footprints. Problem was the footprint is not for the same switches I keep in stock and the pins didn't quite fit. I think you're right I need to just draw a part that I will understand. Thanks for the help!


Edit: So to use this symbol, do you use three symbols and attach them to one footprint? With all 9 pins?

General Questions / Re: Snarkdoodle low output?

Good suggestions, thank you very much. All the resistor are correct. And I definitely have the unbuffered hex inverter.

But checking the values of everything led to an interesting discovery! I have a magnitude problem in one of my capacitors.

Take a guess? Spoiler alert, I noticed 2 100nF caps on the board and there is only one in the BOM. That is correct, instead of 100 pufs I had 100 nanos at C4! I have replaced this with the correct value and the pedal now sounds great. So it comes down to probably the most common problem in my bench, builder error!

Thanks for the advice and support!


General Questions / Snarkdoodle low output?
« on: May 12, 2022, 02:04:41 AM »
Iíve read about the snarkdoodle in the past, and heard itís quite loud. And I watched some Red Llama videos and that seemed quite loud. Now Iíve built a snarkdoodle and at full gain and volume itís barely over the sound of the guitar clean. Iíve got a 1M and s 10k pot in it now. Any ideas why my output would be so low? Anything I should check?

Sorry to wake this one up after so long. How does that SparkFun Stomp Switch part work? It looks like it has three SPST symbols and then it has the familiar 9 pin footprint, three times! I was using a nice template from, but I when I generated the board it had three footprints, one for each symbol. (learning kicad is hard.)

Thanks! Here is a gutshot, and a picture of the jack, where I had to drill a bigger hole and then cover it with an old washer.

I built the free mugshot I got with my last order. It turned out great and makes a nice booster before other pedals. I screwed up the input jack positioning a little and had to put a big washer to get it lined up correctly. I'm new at building and this was a great project ot learn a lot from. I built it in a big 1590B, just for the space. I've tried to enclose an image.

Thanks for the info!


General Questions / What does VFE mean?

New to the forum and the site. I don't hink I'm a robot, but the registration process had that fact in doubt. I'm looking at ordering a few boards and building some pedals, but i don't know what the term VFE means. I don't see many posts on the subject either. Is it a site specific term, or a general term? Thanks,
