Been aching to try this out ever since it was announced at NAMM. Not many stores have it yet, but Pro Guitar Shop does. It appears to be similar to the Slash Octave Fuzz (which I also have), but I want to compare them side by side. If nothing else, I really dig the purple metallic finish LOL.

Quick comparison of the two: Sub Machine is a bit more intuitive to use, and you can use the fuzz on its own--which you can't on the Slash. The Slash seems like it has more gain on tap, and there are separate volume controls for both the up and down octaves. On the Sub Machine, there is only a volume control for the sub octave.
Both pedals have two footswitches--one for effect on/off, and one to toggle the octave up. Both pedals also have a pushbutton to run the sub octave into the fuzz. Here is where they differ: on the Slash, you only get the fuzz effect when this button is engaged (otherwise, you just get the sub octave clean). With the Sub Machine, the button switches from running sub octave and fuzz in serial or in parallel.
As I mentioned, with the Sub Machine, even with the push button in the up (parallel) position and the sub and up octaves off, you still get fuzz. This is what may be the dealbreaker for some people. But the Slash does have its own thing going on, and it's definitely the more agressive of the two. The one good thing about the Slash is that you can get the sub octave effect without fuzz, which is good if you just want clean sub or plan to get your dirt elsewhere (another pedal or your amp).
Bottom line: If you're looking for a great fuzz with up or down octave capabilities, you really can't go wrong with either pedal. I would recommend either one. P.S. I'm not particularly a fan of Slash or GnR, but that's not what drew me to this pedal. It was the feature set and a few postive reviews I read. Originally I was just looking for an analog octave pedal, but this pedal intrigued me.

I was indecisive for a while about which to purchase, the Slash or the Sub Machine. I ended up going the Slash because I already have the la machine and fuzz tone wise it would have been more of the same if I'd purchased the sub machine.
Straight fuzz can be had on the Slash with the pedal engaged , the sub into fuzz engaged and the sub octave knob wound fully CCW, in other words the sub octave is completely removed from the signal.
One thing I found interesting is the octave up can be used without fuzz with the left foot switch not engaged and the right up footswitch engaged. The only control that functions when set-up like this is is the octave up knob. This setting is great for experimenting with both pre and post OD/distortion pedals or directly into a distorted amp.
As Paul L mention above you can get a clean sub octave as well.
This is one extremely flexible pedal and it sounds way better than the majority of internet demos. Even though it's touted as being capable of thick shaggy '70s fuzz in the manual I don't think it gets as woolly or thick as the la machine (I'm yet to do a side by side comparison) but I believe (from listening to internet demos) it is a good compliment to both the la machine and sub machine.
Same as Paul L, I didn't purchase it because of the Slash thing but because of the combination of features. I considered for a good while what I really wanted and am really happy with it.

Funny to see one of my old threads pop up...I've since gotten rid of all my pedals and invested in a Helix (actually it was the other way around...I devoted six months or so into the Helix before I ditched the pedals).

It appears the Sub Machine is about $10 more than La Machine. Assuming that they have the same amount of gain, as the owner of a La Machine, it would be nice to have the octave be foot switchable.
Much like a good swig of apple cider vinegar, it is, however, a fairly potent flavor of fuzz that seems to play very differently with different amps and guitars.
I'd suggest trying before you buy.

The sub machine was released about two months after I bought a la machine. If I'd known MXR were going to do this I would've held of and bought the sub instead and probably wouldn't have gotten the Slash.
You are correct that the la machine reacts to different pups and amps. It is a fun pedal and is enjoyable to experiment with. In comparison the Slash has an edgier tone to it, sounds more mid rangey, and doesn't get quite as woolly.
