«  A must for small club combo, a true marvel of sound »

transistor amplifier with a compressor (single) chorus both commanders via the foot pedal. power must be 70W to 100W with external speaker. Frankly it's 70W of real power, as saying that it develops much more tuned in comparison with other amp. This makes sense, since the power is one thing, but the impression of power is directly related to the sensitivity of HP.
So small Jazz Club style etc is perfect with a drummer + guitarist. If it knocks a little more, just add one more box and it's perfect.
Level adjustment is happiness, there are all what you will, Di XLR, EQ, EFFECT SEND RETURN, DRY DI out POST and PRE EQ etc.. All this in a very small cube. The EQ is very sensitive, for cons, I was not able to know if it was a 4-band EQ with + or - 15dB boost or just a 15 dB, I do not know where is the zero (or at noon to the left.).

UTILIZATION

The config is very simple, you plug and it works, the number of possible connections is welcome, there is always a solution to retrieve or send audio to the amp. All with a sound quality quite remarkable.
I read the opinion of SlapKid on this amp and I can only say that he probably has a faulty amp or hacked, the mine well and sounds even if it is metal, does not vibrate absolutely not. To the right is simply because it is a joint insulation between all the wall of the amplifier, so that each screw locks the wall and seal the same time. If an amp buzz, it may come from the bass, which captures the 50 Hz or 100 Hz, otherwise, the receiver has a concern. I personally do not have that problem is one of the best amps I've had compared to the price. I played on the Polytone, Fender's, the MESAboogie (400 +) and so on.
Then it is true that to disassemble the amp, there are many screws, but I find it comforting, and above all, do not remove all the amp to change HP's twenty screws to remove and it is all. It is much better than the big heavy chipboard screws screwed. it is true that there is not much room, but it makes sense, if you want to do a little amp. )

SOUNDS

So what really makes the most of this amp, in addition to connectivity options, it is the sound, so much that I bought a head 800Rb later so I felt I had found the amp of my dreams. So I have the MB200 for home and small clubs and 800Rb to send heavy.
Sound levels, if you want to play Death Metal Trash, ouliez the MB200 is clearly an amp with finesse and simplicity of adjustment, a wide range of sound, it even accepts 9V pp input. This is clearly an amp for Jazz, I have long used a Warwick fortress one 4 string with it and that's fine, the sound is at once neutral if you want or boosted as desired (efficient EQ) same with a bass. on the other hand, since I was a Fodera 4 string, the sound for me but now I think the bass is also something ))

OVERALL OPINION

I stayed true to GK for 20 years, their vintage stuff is really good. I have more reservations about what comes now under the brand, even though I have not tested, except perhaps the MB150 which is not bad, the series does not inspire me too backline without really knowing why.
In fact I buy 3 MB200, one at the time at full price and two later for the stock. I had a lot of amp hands, poytone, Fender BXR300C, MESABOOGIE 400 +, Glokenglang ...
I completely remake the choice of MB200, besides, I always seeks an opportunity for any components.
Incidentally, the price of this amp seems at least very high for some time, much like the Polytone. Frankly I bought two MB200 at 60 euros each, it's a good price, but even if the amp is quite good, do not put more than 100 euros in this type of stuff old.
Especially since many of these amps generally have the HP HS after storage in humid conditions etc.
If it is to put 300 to 500 euros as I have seen sometimes as many see the side of the MB150 or otherwise.
