jc_riffs Posted July 21, 2019 Share Posted July 21, 2019 Hi, Just after a bit a of advice if anyone has had any experience of this. My GK MB800 Fusion head has been great for the past 24 months, however and a gig last week if started making a terrible white noise hiss through my cabinet. At first I thought it might be a power issue at the venue but when tested it at home the outcome was the same. The noise reduced slightly when the Trebble was rolled off the EQ. I suspect it may be a problem with one of the valves but I’ve never had amp issues so hoping for some help. Dows anyone know of anywhere in the NW that could carry out repairs on this head.
