I've had the chance to set up my Bi-amp rig. Main effects board covers both rigs, this went into the loop of the 'treble' amp.
It's spectacular! Really good hearing it at volume. I like being able to hear distortion, chorus, envelope filters and so on, working on the higher end of my sound while my big bottom remains solid.
I then tried this as a stand alone through a straightforward amp/cab set up. And it's absolutely fine for bass.
If you want distortion then this has every conceivable option. I'm even warming to the idea of reverb on a bass!
Considering the price point this is an excellent option for recording and live work. It ain't a Helix, but it doesn't claim to be. It's not as flexible as a Zoom but the simple way the menu is organised makes it incredibly easy to use and to understand.
The only weakness I've found so far is a small delay when switching between patches. A real issue if you want to bring a different patch in and out during a song.
Definitely needs ironing out.
