A pretty cool variation of MXR Blue Box with a few extra bits and features. The only thing that is a bit unclear is the switch that selects between one octave down, 1/2 octave down and 2 octave down. Original has a 3 position slider switch but I would like to convert to a toggle switch (3PDT on/off/on or DPDT on/on/on?) or maybe a rotary but I'm not sure how to tackle it. Layout has the switch labels per the schematic which can be found in this link: https://music-electronics-forum.com/filedata/fetch?id=829397
*update*7mike_p found a solution for the switch. See hit comment below.
