I'd try swapping out cables to begin with, particularly the cable connecting the head to the cab. Other than that, I wouldn't know where to start. Someone should be along shortly to give more advice than I

How high do you have the treble, and does the cab have a tweeter? As the treble on Markbass amps is set very high, so if you have a lot of it, combined with a tweeter, that could be a lot of it. Using the VLE cuts highs, which would explain the reduction in overhiss.

Hiya lozz, no tweeters on my cabs, maybe the ashdowns don't like my mb amp,lol
