    This amp rocks.
    I play thru 4-10" Celestrians or 2-12" Celestrains and the sound is so diverse.
    Both speakers setups get great sound on highs and lows.
    Its amazing how much changes you can make to your sound with this amp.

    Another bass player friend comes over and hears this and he is awed by the sound compared to his huge Hartke setup.

    This amp produces..
    According to Duff McKagen 25+ years playing on GK without a failure keeps him from ever changing.
    Very reliable so I hear.

    GK 400RB-IV, my trusty ol' friend

    Iíve owned the 400RB-IV for six years now. Originally bought it in college because I needed a cheap and professional sounding amp, and thatís exactly what it is. The 400RB has a unique but versatile voice and I was able to pinpoint MY sound pretty easily. With a pick, I can dig into it and get a real punchy, aggressive punk sound. With fingers playing closer to neck, I get deep reggae or Motown sound Ė all without changing settings.
    At a time when I was touring regularly, my vintage SVT crapped out and I had to go a few weeks with my 400RB backup. Had no problem driving my 8x10, even at outdoor festivals with 2,000+ crowds. Consensus was the GK sounded better, so we didnít even get the SVT fixed, just went and bought a 1001RB as full-time replacement.
    Most important, this thing is durable. I am known for being quite abusive with my gear and this thing has been dropped, rolled down the street, left in the rain and still kicks huge sound today. DI did go out after 5 years, but that was probably more my fault than a quality issue.
