From what Brian says on his site, he's mighty impressed by what it can do. I don't know what features are planned, but I'm very interested in it.
The deacy sound already exists in his VBM Vox amp and it's really good. Not sure what could be built into it. I don't think his delay is really possible, unless there was a stereo fx output. That could work, I guess. Just the sound of his guitar/amp setup in simpler form. What did the Jimi Hendrix pedal have? Wah, distortion effect, etc.
