First, for doing all the work to redesign the circuit and board to accommodate a 3207. Very much appreciated. Not just by me, but by many others, I'm sure.
Second, the layout is very compact. Compact enough, that a person could consider shoving two of them in the same pedal. This creates some interesting possibilities.
First, there is the obvious possibility of splitting a mono input signal and having two asynchronous flanger outputs.
Second, there is the possibility of having a mixer and combining the two flanger signals into a single more complex mono output.
Third, there is the possibility of lifting the dry signal from each flanger outputs, and running them "stereo-out" to separate amps or mixer channels. At slow sweep speeds, this can produce both apparent movement as the phase relationship between left and right keeps changing. It can also produce "flanging in-air" (though that likely requires standing in the sweet spot). At faster sweep speeds, you get stereo vibrato, which can be interesting.
Fourth, with dry lift, and setting one of them to "filter matrix" (non-swept) mode, combining flanger A and B gets you variations of through-zero flanging.
Clearly, throwing a pair of these into a suitably-sized chassis, that can accommodate both boards, a splitter/mixer board, additional jacks and toggles, can yield something truly wonderful.
