I have been using the "Pocket Rock-It Pro" for about a year now. There are several settings to choose from. Clean, an excellent chorus, distortion and extra heavy metal settings. There is also a volume control and filter (small EQ) for extra tweaking. Finally it offers a spot for headphones (which comes with the unit) and axillary input for CD or MP3 jam along backing tracks.

I am glad I chose this mini amplifier. Not bad for $49.00.

The VOX unit looks very interesting. I wonder if it is as good as the AD**VT amplifiers?
