Tell me more about GK - Just plugged my toy MB200 combo into a real cab

    Haven't played a GK in years and no new MB's in town to demo
    Just used the power amp side of an old tiny 1x12 MB200 combo (100 watts) in to a 2x12 cabinet.
    Sounded really good when compared to a 7-Pro; different but really good.
    Also sounded like way more than 100 watts with a solid and firm bottom.

    Does the old MB combos sound like the RB series?
    Do either of these sound like an MB500?
    i.e. is the GK sound baked in and the main differences are power output?

    Bonus question: Does MB500 sounds more like the old MB200 combo than the Fusion?
  2. Toy? And G-K doesn't make a MB200 "combo" - you mean "amp", right?

    Huh? :confused:

    And what real 112 and 212 cabs?
  3. I've only heard RB's in isolation, it's a familiar sound with more growl on tap in the RB's.

    My MB200 is a working tool as much as a cute thing. Everyone says MB500 is a louder MB200.

    Always remember, 500w is but twice as loud as 50w, assuming the speakers are the same and can handle the power.

    Are you sure old MB200 combo is only 100w?
  4. +1. All the MB200's are 200W.
  5. I think Jim C may be talking about this old combo.

    200MB not the MB200. Gallien has always been the conservative side with power ratings and builds in a reserve.
  6. Oh okay - thanks B-String.

    Jim, I still don't understand what you did - added an ext spkr?
  7. The 200MB does have an ext. speaker jack and a switch to turn off the internal speaker if you use a 4 ohm cab. That is likely what he did?
    I have never heard the 200MB with just an external cab.

    Sorry for not being more clear; the 200MB is one of those small metal amps from back in the day. I bought this one used in the mid 80's.
    It has a 12" in a small metal cabinet and allows for an extension speaker with the main speaker on or off. It is rated at 100 watts @ 4 ohms.
    It is a great practice amp and can do small coffeehouse type gigs as the speaker is not so efficient especially in a small cabinet.
    Today I tried just the power amp section into a Dr. Bass 2x12 with a tweeter.
    It was unbelievably loud with the clip light just lighting; easily enough to do a gig with a rock or blues band.

    I suppose this amp is too esoteric for a comparison with either the RB or new MB micros but was hoping there was a geezer to two that still had one kicking around.
    Ironically, just the amp version was for sale in the classifieds last week.
  9. I have one of those 200MB combos like the one pictured, but I haven't tried out any of the newer GK gear at all. I can't tell you how they compare tonally to the newer GK stuff. My 200MB is almost 23 years old and still works fine. :)
