I use a 4-ohm speaker to enjoy the full power of the amp, and 200 watts are more than enough, even when my drummer gets excited.
I bought it for the weight (1 kg) and its small size (it fits in a soft case low lambda).
The case is simple, and the blue LED on / off button is nice.
You plug in 2 seconds Speakon cable to the cabinet.
No need to book - simple adjustments fast and efficient - it goes straight to the point, and not taken cabbage with 68 preset sound or preamp, which for me are the gadgets that are always a bit of a chore to set up - there are pedals for that.
In any case, the shades are met, sound gras with clean sounds, but I corrected a lot of my bass sound too, so I try to stay pretty neutral on the amp to not be too dark, as it has songs with enough styles.
The more = attenuator decibels to move from passive to active low bass when you 2.
It is a pop trio / rock acts both quiet and melodic compositions, and stuff a little more violent with a lot of effects, therefore, contrasting pieces, with a drummer who alternates nags bearings with a super hit end - and the guys are always amazed by the sound quality and volume, despite the style of the song and the size of the box.
I play an active Jazz Bass, and I plug in a cab Eden MB200 12-inch is also relatively compact.
I for the month of June, and I had it in the viewfinder for at least 2 years. I was just waiting to find the right cab 'before I started. I tried more powerful 200-watt GK but me enough. I hesitated with combos, but congestion largest bothered me. So I preferred the small head and small cabinet without regrets. Other brands have not convinced me. I did not know specifically GK before, but the weight / power ratio, sound clarity, price, and look, won the bet. The many positive reviews on this amp certainly strengthening my opinion.
