Good sounding and versatile pedal. Easy to dial in and it has the TonePrint feature which allows for many more options, either download already made ones, or experiment on your own.
In general I am not a big fan of octave up when it sounds too synthetic. This is quite common in many pedals of this kind. But some of the TonePrints handle this better than the two stock settings. The Sub 2 dial goes a bit too deep for my usage, so it is fun to play with in the beginning, but not super useful for guitar for me. But it can also be put to better use by TonePrints. I realize I tend to stick to the Poly mode though and that provides good tone-string separation in my opinion.
The really nice thing is the Sub though. It transforms single coil or humbucker to a Bass guitar. Really cool and nice sound. There might be other options out there that do the same thing and better, but for the price I think Sub'N'Up is really good.
Compared with the mini I also like that I can easily flip between Poly and TonePrint modes.
Pros:
Versatile with ToneRprint
Poly mode has good separation
Sub gives you are very nice sounding bass guitar.
Cons:
A bit synthetic on the stock modes of octave Up.
Sub 2 might be cool, but might depend on the capabilities of your othr gear (amp, speaker, etc)
