Thanks for following up! It's been on my to-do list to give feedback and record some sound clips in the new year.
In the meantime though, here are some initial thoughts:
I was surprised at how small it is. It's also a beautiful design, I really like the color scheme and font choices. Also, the soft touch foot switch is delightful.
I've only been able to play it through headphones and for recording so far, and it's been very, very good. Like others have said, the headphone output is really really loud, I only ever have it up maybe 10% of its capacity. Sound quality is very good. I haven't tried Aux in yet, and I don't expect to any time soon since I didn't buy the OCSD for that.
I haven't notice it adding any noise to my chain. Not sure what the original OCSs were like, but this one is dead quiet.
There was a bit of a learning curve - for any who have it, but aren't really gelling with it yet I say keep trying. I initially was setting it almost flat as possible, with Punch at minimum and flat Mid Response. After a few days I think I found the setting that works best for me:

I'm trying the XLR Out into a Scarlett 2i4 2nd Gen today, so I'll be able to comment on that later.
Now to the juicy part: Now that I've had time with it I don't think I could live without it. I didn't realize my recorded tone was on the sterile side, but the OCSD adds a wonderful somethin' somethin'. It warms up my high gain sound, but in subtle ways that I don't think a para eq could (believe you me, I've tried). It also feels differently, more responsive maybe?
I have a custom blend pedal to go with my high gain Megalith Delta to bring in some low end, and I think the OCSD will be even better then, particularly with some of the baked in sound. With Punch at minimum and Mid Response at flat there's still some added clarity, like slightly boosted 800hz. It's not bad, and I can see it being great in a band setting. Also, I thought the High Response was a simple variable LPF of sorts, but my ears are making me wonder otherwise since the Hi-Fi is closer to the the Vintage/Modern setting I have it at. When solidly in the Modern range, it feels like treble content is boosted quite a bit.
All in all, I would highly recommend this to anyone recording without a cab, it's made my sound much more musical.
