So here's my impressions after a few days of playing. You'll have to take these with a bit of a grain of salt as I don't have a good gig situation right now to put these into a mix.
Overall: Smaller than I expected. Heavy for its size. Pots have solid feel, but some of them were already scratchy by the time they got to me. Switch didn't bother me since I've always been a tapper and not a stomper. Boss switches usually require me to make a conscious effort to hit them hard enough.
Octavium: I went from really liking this one to not liking it a ton this week. The octave down was smooth, but wasn't really as aggressive as I liked. The longer I played with it the less enamored of it I became. I did like the 2 octave down better for tone, but I could barely get it audible with my setup unless I played WAY up on the neck. Maybe I need to biamp with a sub. The other problem was the tracking. It wasn't bad, but wasn't great either. It seemed to decay glitchy which hasn't happened to me on other octave pedals that I have used (BMS, M13, Multiplexer, HOG) unless it was designed glitchy (Pollyanna), or I was playing really low on the neck.
The octave up wasn't bad either, but I think I would have prefered having the tone option on this one as opposed to both of the octaves down. I would have liked to accentuated the highs of the octave up more than I was able.
The biggest problem with the octavium in my setup is the noise. This one seems to really bring on the noise, much more-so than the other two of the tourbox. I wanted to make clips of it with the slow filter on my M13, but the noise of that combination was unbearable. Originally I thought it was my bass needing a new pot that was causing the problem, but none of my basses could bring the noise down. I need to sort out some noise in my recording setup regardless, but the Octavium took a little noise and made it a lot of noise.
If you want to fill out the sound without drawing a ton of attention to yourself, then I'd recommend this to do it if it wasn't for the noise. For any other more obvious purposes, I'd have to recommend something else. If no one else had noise issues with this, then it is probably my stuff causing it.
Bass Distortion: This one grew on me the more I played with it. I owned a ODB-3 a few years ago, and this sounds a lot like I wanted the ODB to sound while I owned it. Similar break up, without the noise or fear of shooting into feedback at the drop of a hat. It is touch sensitive, but it's not very progressive. It has a low gain breakup that slowly gets a little more aggressive, then all of a sudden goes into full distortion breakup, where it continues to clip more slowly till it's really saturated. I could either really like this or really hate this, depending on what I needed the tones for.
EQ doesn't seem to axe the mids by default, but it can.
It has a mix knob, but I don't feel like it NEEDS it.
If I needed an ODB-3 type tone I would absolutely own this pedal.
Moby Dick: I don't generally care for chorus, but I really like this pedal. It is very versatile. From just on the outer edges of experimentation to a barely audible chorus effect and everything in-between. The effect level control allows for extremely wobbly settings to just barely sit on the top of your tone if you want. It will also allow for the dizzyingly wobbly settings to be prominent if you choose. Depth and Rate controls also allow for a wide variety of sounds without being difficult to dial in. Tone knob... is a tone knob. With my limited experience I would call it somewhere in-between watery and icy, but I feel like a little bit of both is in the pedal. In the past I've preferred chorus pedals that sound to my ear as watery.
If I go back to singles from my M13 and start itching for chorus, I will seriously consider this as well. I have no problem recommending this pedal to someone else.
I have to sort through all of my crappy recordings to make them less crappy before I post them. Hopefully I can edit out enough of the crap to make them good

Hope this is helpful.
