I was heading toward two separate builds with a DOD EF440 and Jawari.
But somewhere between 11:30PM and 12:00 they became a 2-in-one pedal.
About that time I had stacked the two PCBs side-by-side using $3 worth of nylon bolts and nuts.
Two mounting holes just happen to line up.

Then I dumped it into a 1590BB and it looked like a good fit.

Slick Job!
I see you figured out the ground planes nicely. Way to make great use of the 'short ends' of the PCB borders where the parts didn't grow.
