Good but bad

The good: well-built for the price; fun to play; tiny. The bad: it sounds terrible through an amp (and you really must play through an amp). The bass notes sound great, but everything else is grotesquely amplified, too--every slight movement of the instrument makes a sound like rustling paper, fingers on the strings thump and literally squeak. Very fun to fool around with, but I can't imagine every playing with other musicians or in front of an audience.
