Sad story that I experienced and was also experienced by several others here at TB is that of many of Ampeg's China-built B200R combos.
Sad because this amp sounded GREAT - one of the best amps I've ever owned - but it was so shoddily built that it began to rattle after about 6 months of moderate (read: non-touring) use. Got to the point where the rattling was a real distraction that rendered the amp useless.
I've read stories of folks who've never had a problem with certain manufacture runs of this amp, and wish I was among them! Notice that this amp has been discontinued.
