I bought the Vox Amplug 2 looking for a way to practice in a manner that is as lightweight and hassle-free as possible: minimum number of cables/equipment; just plug and play.
This is literally it; plug and play.
I keep my headphones connected to this Vox at all times, and all I have to do to start playing is plug it into the guitar. That's it. Top marks for ease-of-use regarding getting started.
The sound quality is excellent; even better than I expected. After you spend some minutes tweaking it to your liking, you're in sound heaven.
Where things could be improved is the way you change the settings. If you only play in one style, this won't affect you. You set it once, and it remembers the setting even after power down. This is excellent. However, if you need to switch, say, from overdrive to clean, or – especially – from chorus to reverb, then you're in trouble. You definitely can't do that mid-song. You need to stop playing, turn the guitar around, and fumble with the controls. Not ideal, but it is what it is.
All in all, however, it's excellent for the price. I'd buy again!
