from my experience:
pros: great idea, ideal for a living room where you also play your guitar. Good tones and possibilities, and decent speaker for music. Looks good.
cons: bluetooth connectivity was bad, it dropped often, crunchy sound with music sometimes, even with the latest firmware. I mean bad, and you had to reconnect the bluetooth each time and "forget the device" to connect to it... Very unreliable. Also my amplifi 150 died within a year, out of the blue like that, never gigged with it (I can't imagine ever gigging with this, I'd be freakin' out the whole time that the thing would let me down). But let's face it, I don't think it has ever been design for shows so...
I just can't recommend this amp. I really, really wanted to love it, I liked the concept but in practice... I don't even know what I want to do with my dead brick now. Do I spend the extra money and try to get it fixed or do I just move on and go another route ( and at this point I am probably done with line 6 after this experience in particular).
So if you can think of other alternatives to line 6 amplifi, please share! I'd like to know...
