From the post
Haven't done a Big Muff layout in a while. This is the Triangle version again and is pretty much the same layout as before, but I changed the orientation of the Tone pot. I was going to build this myself and realized that I didn't like how far down the Tone pot was from the other 2 controls, so I tweaked it a little and I'm happier with it now.
