Really curious about this pedal for headphone / studio stuff for a dry signal with no pedals, I've tried most amp sim plug-ins and I always end up turning them off because I find them a little artificial, but from the demos this sounds a lot better. Anyone know what's actually going on inside the box? Gain, some clever eq, what else?

As Kev replied, it is a combination of carefully designed analog filters. It took a lot of R&D to get the right steepness, corner frequencies, ranges and peaks to recreate the huge span of cabinet tones realistically. Also these filters add an "apparent compression" due to the notches and peaks, so the actual feeling of playing a cabinet is there..
What´s the difference with an EQ? ..EQ´s don´t have enough steepness on their filters and their frequencies are fixed..you can maybe get a cabinet "color" with an eq by boosting and cutting some specific freqs, but they cannot reproduce the really steep high and low filtering and specific Q´s that a cabinet has as a system. You'd need a 20 band, +-40dB per band EQ to get close..
compared to digital, IR cabsims, like the torpedo cab, the OCSD offers instant access to change or adjust your tone on the fly, for that "extra something" you need..IR Cabs are really good, realistic and complex, but they are "preset" based, digital driven, and well..more expensive.. OCSD aims to musicians who want instant tweakability and want to be able to "create" their own cabinet responses , like "vintage top with modern bottom"..and also it is very road worthy and designed for live use..
imagine this situation..you set your IR cabsim perfect for your room and rehearsals..That 4x10 vintage carlsbro cab simulation works perfect..but then..at the live venue..different floor, walls, room size, PA system, the preset is too boomy and all you hear is low end mud..you would have to find a new cabinet preset in a hurry that has the same top end, but different low end...then, edit mode, save, cancel, save preset, assign, etc.. With the OCSD, you just kneel and turn down the resonance down a bit, and adjust the cab size..and bob's your uncle..
