Ah, comb filters too.
The only reason I think this pedal would be great for the Soundblox2 line is because of their interface style. One knob and button combo can do several things, and that's not super common among other builders. For example, something as basic as input and output gain and a 3-band parametric EQ is already anywhere from 8 to 11 knobs for the average pedal. The multifunctionality that SA brings to the table could cut that down to, what, 3 knobs and a couple of buttons?
Looking at an existing SB2 pedal for comparison's sake I can totally imagine one possible way to implement this idea.
The option button on the left (noise gate in this image) could cycle through options like "Bass","Bass Q","Mid","Mid Q", "Treble", "Treble Q" while the one on the right (Tone Shape) could essentially copy the exact layout in the above image.
The drive knob (same location as pictured here) could control the amount of grit added to the signal (going from perfectly clean to a subtle breakup to slightly furry at the extreme) and the output knob would also maintain it's purpose.
I'm not entirely sure what role the center wheel would play here since the option button+knob combo I've described already seems flexible enough to implement a 3-band parametric EQ. Furthermore, I'm not entirely sure what additional benefit trying to cram different filter types in here would have. Correct me if I'm wrong but I feel like there wouldn't be much benefit to multiple bands of low or high pass filtering? Some way to mix filter types seems like the most powerful solution. Admittedly I don't know a tremendous amount about filters, however!
