Amplug 2 Bass : Amazing little piece of hardware

The thing is made out of cheap plastic. The sound is quite hissing. Some of control combinations are quite awkward (press the button, and holding it rotate at the same time dial right next to it). But for the price it's the best thing I've ever bought. If I have 15 minutes to play at 2 am, I just plug it in the bass, connect headphones, and I'm ready to jam with drum tracks included. No need to take out bigger amp, connect the guitar and so on.

Make sure you read the manual, though, or you will be one of those illiterate people who complain that the product description promises 9 drum tracks, and you've got only 3. There are 9, read the manual (though one is, admittedly, a metronome).

And yes, answering the question I had before I've tried the device: it is possible to change the tempo and volume of drum tracks.
