I have this, it's for sale but due to lack of space as opposed to lack of either quality or functionality
There's a few things to say about it
1. I've had similar powered speakers before, I guess most notable the hil Jones PB-300. I've not run them side by side, but given the difference in RRP I was extremely surprised at just how good the Blackstar sounds
2. I run both active and passive basses into the input for both practice and rehearsal and it works just fine, always good to know if you're gigging it
3. It also has a passive speaker input (i.e., bypasses the power amp stage) which I've been using with my Ampeg PF-50 and it sounds absolutely lovely.
4. It looks and feels like a quality unit
In short, if all Blackstar gear is as well made, as functional, and as good sounding is this unit, they're doing something right π
