Travel guitars are always going to be a trade off in respects to sound quality but the Jumbo Junior is as good as any other travel guitar, so if you're happy with that then you'll be fine!
The gig bag it comes with is solid, the guitar seems well built and together it's a light and robust travel companion.
My only real gripe is with the electronics. It's only got a volume and bass knob, making it tricky to dial in the best sound. Also, as with many similar systems, changing the battery is a challenge!
Overall, I'm happy for what I got it for!
