All user reviews of 1/5 for the Gallien Krueger MB112

On paper it's super attractive: a 200-watt amp drives a 12 inches and weighs 13.7 kilos everything and cheap.
The amp is fully digital, switching power supply and output stage switching (class D), the speaker is néodimium, hence the lightweight.
There is a low input with a choice asset / liability, a gain, a serious medium low medium high treble contour switch. Headphone out, entry, exit DI, socket adapter (supplied with a separate power cord).

UTILIZATION

The manual indicates that the DI output is pre gain and pre eq, in reality it is post eq and post gain. The manufacturer, when asked, acknowledged this but did not give any justification.

SOUNDS

The first one I received did not go out any sound from the speaker. As against the headphone output and DI worked. The off switch had a tendency to get stuck on position.
I have returned.
The second I got out the microscopic one, as if we had plugged the speaker on the headphone output. And in addition there was a heavy body that moved freely within, to believe that the speaker had lost its magnet.
I also returned and I'm back, I will not try a third unit.

OVERALL OPINION

Manufacturing quality deplorable, unacceptable. Flee this model as the manufacturer will not be able to make better.
