Actually, I wonder if it's full analog.
Anyway, here he talks about the signal chain:
And here he uses the chorus with sansamp only:
Funny how they packed in that device everything I use on my Zoom B3. I'm gonna replace it with the Flyrig, gonna miss the looper though.
The only time there is any digital in the analog signal path is when the Octafilter section is engaged. How much is digital is dependent on the Mix ratio. The Comp, Boost and SansAmp section is all analog and the Chorus is digital but runs through a parallel mixer so there is no break in the analog signal path.
