Sweet! I will chain them all up tonight and get some recordings going.
Last night I got the box open and spent about 2 hours between the 4 pedals, going back and forth between them because I didn't know if I could chain them and I wanted to be on the safe side.

First impressions:
Blackbox Overdrive:
This guy was interesting, a really nice solid drive tone that could go from sounding super normal to super weird (in the best way) with the extra options.
I found myself usually keeping the blend on full overdrive without any clean tone, gain most of the way cranked and the high pass filter somewhere close to noon or a little less. The toggle switch didn't seem to do a whole lot, it was kind of subtle but I could tell on certain settings it would add a little bit more body to the drive tone. A really interesting tone that I got was to crank the master volume, turn the clean blend a little less than noon to get a lot of clean tone in there, and then crank the high pass filter so it was fried sizzling sitting under your regular signal. I can't wait to stack this guy. It's also plenty loud enough to push your amp. The bias control was really subtle, but added a little texture here and there.
Incinerator:
This guy was pretty crazy. But what I liked most about it was that you could confine all of the craziness to the second footswitch if you wanted to, and have a solid fuzz as your main tone. I quickly realized that every single control is HIGHLY interractive with each other, in general, between modes, for oscillation, etc. It it is LOUD. It has a TON of sustain. A TON. Like better than a Big Muff sustain. Which is nuts. I'm going to test it out tonight to see if it is infinite or not. But anyways, I kind of liked to think of this as a more controllable Noise Swash. You could definitely cop some of the Noise Swash sounds, but instead of being uncontrollable and unpredictable, you can just make the second footswitch do all of that for you. The middle top knob is really, really interesting. Depending on how the knobs and switches are set, it can be volume, oscillation control, and a FILTER SWEEP. Like WHAT? I noticed that the middle knob works in conjunction with the far right knob for volume between the modes. It can go from a pretty organic crunch, to a synthy sort of squeeze, to a distortion, to a gated fuzz, to oscillating maddness. I feel a LONG video demo coming.
Squarewave Generator: I didn't spend a whole lot of time with this guy last night just because I got to use Derelict's weekend before last. But I'm looking forward to recording the demo of it! It is LOUD.
Reverb Machine (RM-1N): SUPER REALLY REALLY AWESOMELY INTERESTING and the one I spent the most with last night. I'm a reverb junky, and more importantly, I like weird reverbs, so this was right up my alley. The first thing that I noticed is that it is incredibly LOUD which is great. I love pedals with a ton of volume on tap. I think the extra controls on this guy give it a lot of noisy opportunities. The feedback control can go from subtle kind of lingering, to full on oscillation depending on how you have the other knobs set. I found that the pre and post gain knobs were really interactive, both in terms of how the reverb behaved, and the amount of gain/drive to the signal. I found it a little bit difficult to get a purely clean reverb signal without a little bit of drive, but that's my favorite sound anyways so I can't complain to hard. It WAS possible, it just took a little bit of tweaking. Pregain up pretty high, post gain down a little low, and you get a mostly clean reverb signal. The drone knob was also very, very interesting. It seems to almost add noise into the signal of the delay path, and the way that I had it set made it sound like a dying reverb tank which was AWESOME. This knob was also super interactive with the others, it could go from just a little noise when you strummed, to full on oscillation (but still a little different from the feedback knob). The tone knob seemed to be a standard high end roll off type deal which was nice to let some of the insanity through without drowing out the rest of your signal.
More thoughts and videos tonight hopefully!
