Simply Amazing!

I have used my MB200 for a month now and am simply amazed. The tone is wondeful just set flat. I can add just a touch of of any control to tweak the sound I am looking for. Just hit the contour switch and you have a great slap sound. It has more power than the 200 watt rating. It fits fine in my bass gig bag. Sweetwater got it to me in three days and their customer service is great as usual. I have purchased at least a dozen items from Sweetwater and have never been disappointed. Thanks tomy rep, Ryan Wiltermood) for great service everytime I make a purchase.The MB200 is a great addition to my arsenal and I will use it much more than I planned. Simple to use with a great GK sound.

Mighty Might

This little head kicks butt. I couldn't believe how good it sounds! Of course, I would expect nothing less from the leader in bass amplification for decades. GK's 4-band EQ is and always has been awesome. Sounds outstanding with my 12" cabinet, with plently of power, room-shaking lows and crisp highs to please any discerning ear. The only disappointment was that the Speakon connector on the back spec was changed so it does not accept 1/4" cables in the center like the original specification states, but all in all very pleased.

G-K MB200

Once again G-K hits it out of the park with this little beauty. At only 2 lbs. I wasn't expecting what I was about to experience, even from G-K. I was completely blown away! I have an MB500 and the tone and power from this little amp was so comparable that I dare anyone to take a blindfold test and tell which one you're listening to using the same speaker cabs for both. The only difference is the ability of the MB500 to reach higher volume output levels, however, I can't think of a local gig that I do where the MB200 isn't enough to handle it. this is far and away THE BEST BASS AMP ON THE PLANET FOR THE MONEY!! I recommend it highly, and I have been playing professionally for 50 yrs come this July and have owned several bass rigs. I am also very impressed and satisfied with the professionalism and service I have received from Sweetwater.

Like Whoa!

This little two-pound wonder is the only amp I've had that didn't need a pedal to make my Alembic sound like it should! I have Peavey combos and GenzBenz heads and numerous speaker cab combinations but I've never been truly satisfied with my sound until this "Made in USA" marvel came along. I'm seriously considering changing my allegiance to G-K!
Music background: I used to gig but nowadays I'm happy just jammin' with friends! \m/

Good things can come in small packages!

I purchased this to use for small gigs and as a backup. I use an Eden WT550 head with 410L and 1212L Schroeder cabinets. This little amp kicks and has a great sound. I set the controls flat adding a little bass with the contour up. It sounds so good I intend to use it most of the time.
