Bought this after much deliberation and looking at other products. I bought a mains adaptor as well as I don't want to be buying loads of batteries. What a good product. The sounds that come from it are really very good. I'm not a professional musician just someone who enjoys messing around and learning new tunes. I haven't found any problems with it at all. I do advise that once you've bought one go on line and look for the Line 6 manual which lists all the presets. You can then start playing with it. It is light and may have a tendancy to fall from the table or bench etc. I also bought some Sony headphones with it so I don't disturb the neighbours. I have read of people using these on stage at gigs and having no problems. All in all a very good purchase for the price. Thoroughly recommended. Try it.
