Thats a hard lesson!! I did the same. I was lucky it was a fuzz face style pedal and the ground plane, not being placed of the ground net, didn't really mess it up too much. And now thats the first thing I double check. haha!! I'm having a tough time with potentiometer placement. I've sent out 3 PCB's now, but they are 2 or 1 pot pedals. I have a 3 pot pedal almost done, but crossing my fingers they don't line up improperly. I'll do a bit more research before I send that one out.

As @finebyfine stated, ground pour only after all is connected and make sure to “Hide Net ratlines” for the ground net.

I’ll have ti find that hide net ratlines option. Quick glance i didnt when i was messing with it last night. Kept throwing me off.

If you hover over a ground pad that’s connected to the ground net and right click you’ll see it.

I use 0.5 mm for everything.

I’ve read the same thing before but I’m pretty sure at the currents and voltages we’re using in guitar pedals it doesn’t really matter. If you look up trace width calculators and guidelines even the diptrace default (2.54mm) satisfies them for practically all pedal circuits.
That said, I still use wider traces for power nets (after voltage dividers and pots as well) but really only out of habit and from my file templates. If it makes routing difficult or causes the ground pour to have gaps I’ll lower them and haven’t had any issues with the boards I’ve done that with. Again not an expert and might be talking out of my ass

I just took one of roberts boards and blatantly ripped it off
I am spacing mine like this and can use the keech template I do everything in MM I make 0,0 my center and highest point for any component. so my pots are if I was to do six pots: (-20,0) (0,0) (20,0) (-20,-25) (-0, -25) (20, -25). Switches are placed at -10 and I try to only put them in that second row. But if you have to put them in the top and do a notch thing they would be at 15. everything lined up with the drill templates from robert using those for me. Figured why reinvent the wheel

For panelizing like stomp switch board. Does the V scoring vs. tab routing matter much? I'm assuming it more of a personal preference, the tab thing looked like there was a lot more possibility of screwing it up lol. Then I just hit panel by customer and enter what my columns/rows are? So if I have 16 boards in my panel, I'd just enter 4 and 4?

You can squeeze more breakout boards into a 100x100mm panel using V-scoring.
Break tabs take up space and leave splinters.
If your Gerber file is already panelized properly and it's all the same layout you don't have to do anything, just upload the Gerber as normal.
I never touch the "Panel by customer" options or the row/column quantities.

Interesting. I did some research on V-scoring, but cant seem to utilize it. Is this done when ordering pcb's from whatever manufacture you choose, or done in whatever program you use to create the PCB. I use JLCPCB as well and Diptrace. I too am making custom breakout boards for some PCB's I designed as well and would like to get the most bang for my buck. All I could do though, is design one break out board. When I tried to add another board outline, it took the original board outline away. So, I'm assuming I need to make a specific size board outline and use the silk scream as the board outline for all the internal breakout boards? The only thing I'm lost on, aside from the board outline haha, is a way to be able to get all the internal breakout boards scored or perforated so I can easily break them out when needed. Thanks!

Awesome!!! So easy and the answer was right in front of me!! I don't think I can count how many times you've saved me a day of headaches! Thanks again!

Sorry to ask so many questions, but with V-scoring, will JLCPCB know where to score the board? The reason I ask is because I did send out a PCB to them with the V-scoring. But when I upload the gerber, and check out the gerber viewer, it doesn't look like its scored. I see where the scoring should be, but it's not cut out on the gerber viewer. Probably over thinking it, and I have nothing to lose really for $5 I guess, haha. Thanks!
