I recently built a SHO-clone for a buddy using Rullywow's OSHpark board (3$ for 3 boards is hard to beat). And since it was OSH park, I have 2 spares to play with, and I was wondering if I could adapt them to a Super Duper.
I'm pretty sure its possible, but I would like to have my logic checked before I start tossing solder around.
The Rullywow build doc: http://www.rullywow.com/build_docs/fo-SHO%20v1.1.PDF
The Super Duper schematic:

So if I am reading this correctly, The first (from input) board is built to spec, and its output goes to switch 1 as output, to switch 2 as input, to board 2 input.
Board 2 is build mostly to spec, with R4 replaced with a 100kA pot, lug 1 wired to the top R4 pad, lug 2 becomes the output, and lug 3 wired to the bottom pad of R4. (or should I have 3 on top and 1 to ground?)
Anything I'm missing here? The rullywow boards lack the power filtering of that schematic, but easy enough to add in if necessary. (the standalone I built is shockingly quiet without it, given my noisy wiring, but doubling the gain may change that).
