Turns out the Southland is pretty much the same circuit as the Lightspeed, but with some hard clipping diodes thrown in the middle (and a couple value tweaks). Figured I'd make a new layout with space for the diodes. This layout uses the same drill template as the Lightspeed.
I ended up building a 2-in-1 with this and a Lightspeed and highly recommend it. If you'd rather a fabricated board, check out the LightLand on the store.
