Can someone please check my layout? I think it's good, but a different set of eyes may see something I missed (and I've never done my own layout before).
Here's the schematic:

And here's my layout:

Thanks!

Looks good to me.
You don't need the 1M pulldown at the end though
as the .1 output cap will discharge through the 50K
volume pot.
PCB layout wise, if you rotate that transistor counter-clockwise 90 degrees your traces could cleanly route to it more directly, but might not have to depending on its physical placement.

Yay! I did the layout correctly. I will get rid of the 1M at the end. Thanks!

A dumb question on my part because I don't know and trying to learn - is it normal for the positive side of a cap to be grounded?

Thanks, Steve. The issue is that I want the transistor part number clearly visible. The boost sounds super evil and the number printed on the transistor is "666"! That needs to take precedence!!

The pedal is negative supply, so the positive goes to ground.
