Hi,
I'm new to valve amps and have a question. I recently bought a Laney cub 12R and so far I'm happy with it except for one issue: When I turn up the gain and the master volume past a certain level and play I notice a sort of fizzing sound coming from the amp. It's over and above the overdrive sound, almost like it's a high frequency mechanical rattle coming from the cabinet or speaker. At even higher volumes this becomes more prominent up to a level where it's really irritating. It never seems to change frequency, but seems like some soft of noise being generated somewhere. This occurs only when playing at gain settings of above 3 on the amp. Having no previous experience I don't know whether this is normal, or if there is something wrong with my amp and I need to do something about it.
Please advise???
