    if your running one 4 x 10 cab with this head should you turn the high volume down..max the low end volume and control the volume with the master..thats what the manual said..i find the cabinet distorts sometimes..im wondering if thats the problem..its a ampeg classic cab..60 percent of the time it great..but sometimes it becomes real distorted..iv tried other cab and the same thing happens..just had the head serviced
    and it happened again at my last gig..its horrible being on stage wondering if its gonna happen ..any suggestions would be greatly appreciated...thanxxx

    I've been playing GKs for over 15 years. I've owned the 400B, 800RB, and now I have a 1001RB.

    For clean punchy sound pushing a full range cab: run the master low on full, the preamp volume (the left most volume nob) between 9 and 12 o'clock. BTW, I never run the preamp volume past 1 o'clock. If you need additional volume, turn the boost nob up slightly (I never ran it higher than 10 o'clock).

    You'll be getting a full 300 watts of power if your cab is 4 ohms. If it's 8 ohms, you be getting about 200 watts, I think.

    Good luck and enjoy.

    Probably your settings.

    On GKs, if you run the preamp volume higher than the master volume, you will get distortion.
