Turns out (and I should have noticed this on the other build) that the EBB (which I did last week) and the Flow are IDENTICAL except for the front panel and the microcontroller, you could swap these and get the other unit.
But it deserves its own build guide since you, viewer, might just have the one and searched for that.
Pretty straightforward build, 3-4th kit worthy.
And an interesting LFO in the end, particularly the chaotic waveform it can produce
