Sounds great with a Bose Sound Link. All this fits in my gig bag which I have in the boot of my car so I can practice anytime I'm away from my studio/practice room.
I'm not bothered or concerned about the plastic case. Sure you can use this live but lets be honest its a practice tool. If you want something really road worthy be prepared to pay for that quality. This is cheap, sounds great and feels good for digital, it is versatile and portable.
Only thing I would like to see in a future update or revision is the ability to transpose the guitar so not to have to carry around different guitars with different tuning. Neural DSP nailed this feature in their more recent products.
