From the post
Like many, I find myself working from home for the foreseeable future due to the COVID-19 pandemic. Most of my time so far has been trying to accomplish my day job in sweatpants and help my wife do hers (aka, kid wrangling), and I haven't had much time to build anything. But yesterday I did carve some time out to create today's layout. Shout out and thanks to Simon from JSA Effect Pedals for sharing some of his creations with me. Check him out on Instagram for build notes on this particular circuit. It's a pretty simple drive and should go together pretty quickly if you have all the parts on hand. And if you don't, he's got some notes on alternatives. Enjoy and stay well folks. Thinking of you all.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Effects Layouts (blog). No KiCad fragment has been drawn for this circuit yet.
