The pedalboard

The board has a config sheet (signal order, power draw per pedal) and a log of what I changed and what it did. The log matters more than the sheet. Six months later nobody remembers whether the buzz went away when the volume pedal came out or only got quieter.

The buzz is the story I tell about it. A slight hum stayed with the volume pedal removed. A much bigger one came back with it plugged in. I treated that as one problem for about a month. It was two.
