Gruntbox v.1 build docs?

[ahiddentableau]

I was cleaning out the old hobby drawer and I came across an ancient green madbean PCB that I had no idea I had. It's a Gruntbox v.1 [(c) 2009 madbeanpedals(!!!)].  Any chance of getting the build docs for this?  I haven't fully traced it but the first part is identical to the current Mudbunny w/just a small change to the power section.  Anyway, any info would be appreciated.

I'm surprised I still had this!
