It can be hit or miss about the absolute sound quality of some of these products. And as others have said you have to make sure they are in proper working order. Craigslist is an excellent source of these products. You can find them for under $100, throw another $100 in for cleaning and repairs and you'll end up with a very workable second or third system amp.
That said, at best the amps sound okay to good. One thing that is indisputable is that the tuner sections are excellent and easily keep up with best of modern tuners.
