    Hi there ... I have a Hartke 3500 head and can offer a bit of advice.

    I am not sure what your EQ looks like but try trimming the 8Khz if what you are describing is high freq hiss. You can also work the high contour down toward -3. Neither of these trims should cause you a major loss in highs and might help with the hiss situation.

    If it is a true buzz you are hearing first be suspicious of your guitar cord. There is also a possibility that there is a fault within the amp. If possible, you might try your gear with a different Hartke in a store and see if the problem still exists. Helps to isolate that cause.

    Now that I have a righteous cab to go with the head, I run my 3500 head on a flat EQ (0) with high contour also at 0. There is no hum or hiss present at all.
