I hadn't heard of high failure rates with Markbass??
They spend alot of money, both online and in print, so that you don't. If their QC was half what their PR is, they'd be the best amps in the world. Their failure rates are not spectacularly high, but they ARE higher than they are touted and higher than should be acceptable. Another dirty little secret about ALL the new switching amps is that they are disposable. Big problems
can be repaired, but at near or more than the cost of a new one. They also have about half or less the lifespan of a normal s/s amp under optimal conditions; I don't like that.
Certainly would make bright doorstop or paperweight. What else would you recomend in the light/class D type amps?
...the aforementioned Genz Benz Shuttles.
Any track record on the new Marshall stuff?
...none that I'm aware of.
Bass players just don't buy new Marshalls.
