I bought the 150 (450 out the door at GC) and its performing as advertised. I load up my playlists and jam along to practice and I bring it to rehearsal because its easy. No problem in volume jamming along with a drummer, keyboard player, bass, 4 vocal mics and a PA. For what it cost, Im good with it. If i HAD to gig with it (I never will, but if I had to) I'd get by just fine I suspect. Anyone else? Reading lots of com[plaints here. Some valid, others a bit unrealistic. It was 450 bucks, Fractal Axe FX II and similar will set you back considerably more. This is prosumer stuff, take it for what it is.
