From the post
Some says this is a HM2 killer. I don't know about that but it differs enough circuit wise to deserve its own layout. Note that "Hard/Soft" switch is omitted as well as "Output 2" op amp circuit.
Factory schematic is a mess so I had to draw up a cleaner version. Electronic switching, buffered bypass and "Hard/Soft" switch is not included.
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 Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
