I got mine a couple of days ago and have had a few opportunities to dig into it. For context, I've had a POG 2 for the last few years and while I can get good sounds out of it, I've never been in love with it...always felt a bit digital and 'lo-fi' for my taste, so when I saw the pre-order emails come up I jumped on it. For even more context, there's really three things I personally use an octave generator for - 1) one octave down mixed into a unity signal with a fast attack for the Jack White type sound and 2) an organ type sound I can use for swells and 3) A combination of an octave down and octave up blended in with my signal to give me really fat tone on single notes. That said, here's my take: PROS: Tracking is solid. Hard to say if its better or worse than the POG, but I do feel that my original signal (when not in full wet mode) responds a bit faster than the POG does while the pedal is engaged. The low end on this thing is glorious. Definitely much higher quality than the POG. I had sooooo much fun playing with it. Nice size footprint (noticeably smaller than the POG2) Soft-switches Artwork is pretty sick Probably one of the biggest pros for me is the simplicity of the controls. The POG is simple enough, but I don't need 8 presets and finding unity gain on my original signal w/the POG wasn't always straightforward. The Luminary simplifies this with essentially 4 sounds and clearer mixing of unity signal. I found that the simplicity inspired me to be 'less afraid' on trying new things and tweaking, etc., which means I had more fun with it. In general, the octave signals feel truer to your original signal than compared to the POG (although the POG is purposefully trying to make it sound a bit different, so this isn't a knock on the POG). I find this valuable. CONS: It can glitch pretty bad when the attack is at 0 and you're using all four octaves (truthfully I think its mostly the -2 octave that causes the trouble). Fortunately I don't really need all four octaves with a fast attack...I usually just use -1 down and +1 up which tracks relatively well at low attack settings. At times the upper octaves feel brittle when the attack is at zero, so YMMV. Which leads me to my next point. I didn't find the filter to be all that usable past 12 o'clock and at lower settings less than 12 o'clock, it has an envelope filter thing going on. I personally would prefer a high-end roll-off or low-pass filter that was a bit more organic in taming the highs. I'm not a "seasick" sound kind of guy, so I personally don't find the flutter control useful. While that's personal preference, I will say that the flutter depth is set pretty high and there's no ability to control it, so you'll either be stuck with a really modulated sound or none at all. It might have been nice to offer a way to control depth which would have made flutter far more usable for me. Some other notes: Requires 250mA of power which is a tad bit more than the POG2. Top mounted input/output jacks which depending on your layout would be a good or bad thing The power receptacle is interesting...you're really need to push it in there, but once its in, it seems pretty tight. In the end, I'm about 95% sure it will be knocking my POG2 off of my board. I'll try and get some clips up later this week when I get more time, but wanted to share my thoughts in case they're helpful for others.
