Finally went through the demo patches this afternoon, checking them out, equalizing levels, etc. Some of them have little surprises, like the octaver that's in the reggae patch, but not turned on.
I HATE the Big Muff model. Fizzy, tizzy and annoying, just like the first one I bought, around 1972. There's a nice bit of transparent OD tucked away in the DI5 effect, though. Just a gentle, tubey grind- much more to the taste of a clean freak like me...
The modulated reverb is good, as are the hall and plate.
The filters are way better than the weak ones I have in JamUp and Amplitube on my iPad. Better than my old POD XT Live as well, I think...
The Jaco patch sounds better than anything I was able to dial up with the de-fret effect alone. I still don't like it, though.
