Does anyone own this?  How does it sound?

I have slide acoustic and electric, and they are both WONDERFUL! ALL the OTS products are exception, I own most of them and use them constantly, although I haven't used the slides much recently due to what I've been recording. But they are playable, sound great, easy to use, etc. etc. etc. 

Yes...and, once you get the hang of it...it's quite nice...
especially for Country, Ballads, and Pink Floyd 

It's what you'd expect from OTS, very nice indeed. I reviewed it here. In that review I linked to a tune I recorded that uses several OTS products - Stratosphere, Rick and Acoustic Slide. The slide guitar carries the melody in the last verse, but you might not recognize it as an acoustic guitar because it's amplified.

Great read, Bit!  I would LOVE to see how you managed to create all the subtly nuances of Stratosphere... a video walkthru, similar to how Zircon does his for  shreddage... would be priceless... I'll donate an immediate 25$ to the effort....Heck, if I had 10K in the bank rather than $500 I'd send you $500 to fund it! And I'm sure Greg would LOVE it also.
 
btw, love both of OTs slides but can't get even close to what the BitMaster does... I'm in awe!

It would be a boring video, I'm afraid. It's 60% using the pitch and mod wheels during the performance and 40% tedious MIDI editing afterward, to make sure pitch bends end up at the right frequency.
