    Comments about Gallien-Krueger MB Fusion 500W Tube Preamp Ultra Light Bass Amp Head:

    I run the MB Fusion 500 through GK Generation One 2X12 and 1X12 cabinets, or two 1X12 cabinets, and that combination rules the stage; indoors or out. The three 12AX7 tube preamp on the MB Fusion 500 provides the warmth that a pure solid state head wishes it could have. The power behind 500 watts is more than enough to meet my needs, but it's a blast to hear (and feel) when it is unleashed with three 12 inch drivers. Cannot get a bad sound out of any my basses (Fender, Rick, Yamaha, Gibson or Epi Elitist). GK is a great company that will stand by their products, and its customers.

    best bass amp i've ever owned

    By robert

    from santa clarita, ca

    Comments about Gallien-Krueger MB Fusion 500W Tube Preamp Ultra Light Bass Amp Head:

    i have been playing 'forever'. i was very much an SWR fan...until i bought this amp. i own a number of basses but most regularly use my ibanez sr755 and fretless p-bass (when my shoulder isn't sore). i was using a peavey bass amp and, occasionally a line 6 LD150 and running out of headroom. not that we play loud, but the 'beef' was missing and the speakers were starting to flubber. so i borrowed this amp and a schroeder 1512L cabinet. awesome. that's pretty much all i can say. well worth the money, no question. i will be happy with this probably until i go completely deaf :)

    The best lightweight head on the market

    By Jerm

    from Hamilton, Ontario

    Comments about Gallien-Krueger MB Fusion 500W Tube Preamp Ultra Light Bass Amp Head:

    Bought this head new and let me tell you, it is one of the best heads on the market. The sounds you can get are awsome, the tube warmth is fantastic on this little head and loud as hell, i have played a 59 p-bass, Jass Bass, Stingray, 4003 Rickenbacker and a Lakeland usa Bass with the heads and i cant get a bad sound with any of these's Basses with the MB Fusion Head. First thing i did after playing live with this head was to sell my Little Mark 3 Head Because i knew i would not use the Little Mark head Again. Just Go Try one of These's heads out for youself. Gk has a winner here People.
