Nice! That works.

I found this one in my stuff.  Not quite the same but a close variant.

Well by some strange coincidence I was looking for a schematic on my old laptop and I came across
this:  The schematic for the Reagun/ Vesta Fire distortion,
https://www.freestompboxes.org/viewtopic.php?t=30739

The circuit is virtually identical to the Washburn, down to the subtle 47pF cap at the input.  However, the recovery stage of the Reagun has more gain than the Washburn.   The switching is obviously different.
