Gallien Krueger MB Fusion 800

DerekB, 05.06.2014
Having used many GK amps and combos over the years this little amp is another winner from GK. I previously had the GK MB800 before this and decided to upgrade for the warmer valve sound. This amp ticks all the boxes, very light, powerful, 2 switchable channels, controls you can see in the dark, multiple ins and outs. I did a side by side comparison test between this and my back up amp an Eden Traveler 550 and the difference in tight bass end and power is quite remarkable....and it's cheaper!

Theoretically good but practical ...

... it looks something different.
The values ??bribe at first sight and I have waited very long on this model.
Tube preamp, class D power amp, many connection and control possibilities in a small space and with the lowest weight.
The sound and the volume convinced me the first time. The low weight, with the offered equipment were my purchase criteria.

Unfortunately, on the first device the controls very strong and the fans clattered so loud that one might think that due to the small size of the device some cables had to be passed too close to the fan rotor.
Then it went back then for this device.

On the second run everything looked much better. The fan did not clatter, the potentiometers could be rotated evenly and without a hakel. The thick end hid itself now however in the DI-Out, which on the mixer independent of the earthing an oscillating, high-frequency whistling / sums as in the transmitter search of an old radio. Trying different cables and mixing consoles unfortunately brought no change.
So it was said here: unfortunately back.

The device has without question sound quality, but the initial trust has been lost by the lack of processing unfortunately.
I recommend GK to rework its series once again or at least to raise the standards in manufacturing.

I will now look heavily for another model.

Thanks to the friendly Thomann staff, the exchange and return was easy.

Though there are other options, the stack remains a rock icon, and is still the most flexible form of guitar amp­li­fic­a­tion.
