I've noticed this with mine as well. One thing that I've tried that helps the fartiness when pushing the PRE knob is running at a higher voltage. I'm able to get more out of it at 18V than at 9V. Of course this works better if you've over-specced your capacitors. 25V (which is what is...

Oh yeah sorry I forgot to mention - I will probably build this with SMD for myself so I was looking for ~equivalent JFETs and the 209s look close enough so I penciled them in on the schematic. I forgot to change the silkscreen for the through-hole layout but it'd be the two types you mentioned...

I'll bite. I'm not an expert here in the least, but - Using honkin' 1/2W or 1W resistors is gonna run at odds with your design goals of unifying your pedals in some big uberpedal. Even laying out with SMD components, a Phase90 is gonna fill up a lot of a 125B enclosure, let alone all of the...

This for sure, use hierarchical sheets -- they're super handy for keeping logical components separate. In my template, I have a second sheet under the first empty sheet that starts out with the jacks and power and all of that stuff. I've also found it really helpful when designing something...

What the heck, was looking for an excuse to test drive KiCad 10! (Still not sure if I like it. DRC and zone fills are so much slower. And it's back to doing the thing where it crashes if you run DRC after making too many changes)

I wonder if you could do a custom 3d-Printed washer/grommet to do the slot/tombstone style. Oh, or maybe you could do a faceplate (sideplate?) on that side to mostly hide the slots. (Though I'm not sure how you'd have that drilled, I dunno if Tayda can do it and it seems like a hassle to do at...

I have a little script to push a new effects directory -- requires: * 'gh' command line tool to make repos on github from the command line * A .gitignore file somewhere (I copy direct from my home directory, you may want to copy from somewhere else) * Ideally, git / gh commands configured...

Oh! And another benefit of faceplates that I thought of, but forgot to write down. You can order a ton of pre-drilled enclosures from Tayda with all of the holes that you could need already drilled, and then the faceplate covers up any holes that you don't use. e.g. you could order a bunch of...

Thanks so much for writing this guide for making faceplates! I created a few and got them in today and they turned out great! I created a new template in my templates directory so it's only a matter of a few minutes for me to create a faceplate for one of my pedals (assuming I'm happy with...

For what it's worth, I've been completely unable to add new projects via the KiCad UI. I have gotten it working by making the initial commit from the command line -- once I do that, I've been able to use the KiCad UI. I think if you get the command line tools working without authentication...

I think it matters less for AC (signal), but for DC there's a pretty strong de-rating curve - the capacitance gets less as the voltage gets higher. The package size is actually relevant here as well, with physically larger capacitors losing less capacitance with a DC offset. I use X7R 1206 50V...

Nothing that I've seen that is SMD and super small for the audio path. JLC will wave solder in a film capacitor for you, though. (C125386 is a the box film capacitor I use, 4.5mm wide). This is usually what I do for values between ~220nf -> 1uF. The first through-hole component you add costs...

Also there are not a large number of circuits that use PNP transistors, which is why they're fairly plentiful relative to the NPN varieties. (I think a couple of fuzz face types, but even those have largely been adapted to use NPN)

+1 for sovcom, the russian D9(x) diodes work in a lot of places that call for a Ge diode. But yeah the BAT41 diodes have a pretty similar voltage curve as the Ge diodes, and they're a lot easier to come by. When it comes to diodes/transistors, the original part number is generally kind of a...

I put together a layout for this over the weekend - I'll probably have it in my hands in a couple weeks when I get my next batch of stuff from JLC. If it sounds good, I'll share the gerbers with @Chuck D. Bones 's blessing.

That looks like an ESP32 module or similar there in the middle - is there a sufficient antenna keepout there? IIRC it wants some space around the antenna but it looks like it has copper right up to it, and maybe even traces underneath. Also putting it right next to the tube might cause RF...

With the @bean 's blessing, I could map this out and post the gerbers. (But if he's gonna re-issue PCBs I'd hold off of course)

b b b b b b b b b b I dunno what you use to generate the gerbers, but the Bouni tools have a plugin that works very well which you can configure to force-fill zones before export. Of course that doesn't help if you fill the zones and cause some kind of DRC problem, but at least it's something...

Is it possible that you dragged one of those components a tiny bit, and generated your gerbers before running a zone refill? If you move a component just a little bit, it's easy to drag it into a ground plane fill. (ask me how I know). The default when you run DRC is to fill zones first, so if...

That's really odd. Does it make that noise in the bypassed position as well? With IC1 pulled? The fact that there's noise on your input, and there are negative voltages on the first input half of IC1 makes me think that something has gone wrong very early in the signal chain, maybe even on...
