Here's my initial reaction to receiving my OCSD yesterday, which I posted in the OCSD thread.

"The sky's a little bluer this morning. The sun's shining a little bit brighter. The birds are singing just a little sweeter. Can you hear it? No? Maybe it's just me. Maybe it's because my OCSD showed up last night, all unexpected-like. It somehow eluded the final stages of tracking and showed up at my door like a sneaky little pedal ninja! It is such a feeling of relief. I can now move on with my life. No more checking for tracking updates ever 10 minutes. No more watching videos on Youtube hoping my stuff will someday sound that good. It's here. And it does.
I've only had half an hour to play with it so far. But that's all it took to know that this pedal will forever change my direct-only setup for the better. I already have it dialed in on a great tone. The knobs are very intuitive and work well together. At the extremes it can sound a bit ridiculous (like if you max or min the knobs), but in that sweet spot, it is oh so sweet. And it does indeed make my drive pedals sound less farty and more like an actual overdriven amp. And as an added bonus, the headphone amp works like a charm, so I don't have to plug my pedalboard into my USB recording interface anymore to practice. I A/B'd it with the speaker sim on my VT Bass DI, and there is just no comparison. It makes the VT sound like a toy. I will say, though, that I don't think I can quite get rid of the VT just yet. I'm going to leave it in the chain - probably right before the OCSD - to use as a preamp and EQ, bypassing its speaker sim capabilities, because I still feel that my passive basses can benefit from the gain boost and external EQ control. There are other (maybe better) options for this purpose, of course, but I already have this one and don't have to buy something else, so it wins for now.
High response around 10:00. Cab size and resonance around 3:00. Punch at 10:00. Mid response at 1-2:00. Pure bliss.
The wait almost literally killed me, but it was totally worth it. I can safely say this is the most important pedal I have ever purchased. And I've purchased a heck of a lot of pedals over the years. Well, maybe my tuner was more important, technically speaking, but not nearly as fun. Well done,
@Dsmnoisemaker!
Now, if you'll excuse me, I need to go re-audition a few overdrive/distortion pedals I was on the verge of selling to see if this bad boy breathes new life into them."
The significant difference between the OCSD and other cab sims I have tried (ADA GCS-2, Tech 21 Sans Amp, VT Bass DI, Palmer PDI-09 [the direct box version], Digitech CabDryVR, Tech 21 Blonde, Aguilar Tone Hammer [AGS mode]) is the infinite tweakability the OCSD gives you. And the real secret to me is in the "resonance" knob. It gives you that "whump whump" sound (for lack of a better description) that simulates the movement of a speaker. At least that's how I'd describe it. It makes it sound incredibly life-like. I got close to that with the ADA GCS-2, but it wasn't nearly tweakable enough for me. The OCSD is an incredible beast. Worth every penny to me.
