Nice piece of gear!
I bought this for my Dad who'd recently started playing bass. I own an RP1000 guitar multi-fx unit and knew from experience that Digitech units were well made, durable and offered a lot of usable features, so really, the quality and usefulness of this thing were no surprise.
What was a surprise was how much my Dad loved the unit and because of that, he's been playing and practicing more, and the aux- and headphone jacks mean that he can learn by playing along to his favorite records, the tunes that made him want to play in the first place.
I can't speak to the quality of the patches or ease of use firsthand, but my Dad is a complete novice, and this thing makes him want to play more. All the time in fact. Every time I call him, he's playing.
Any piece of kit that makes you want to play more is a good purchase, IMHO.
And of course, the Sweetwater staff are the best in the industry. My Sales Engineer was out of the office, but another staff member took great care of me.
