    Hi I have a new Ashdown ABM 500 evo 3 head, when i put the valve drive on, even at a low setting' I get a buzzing noise, it does not affect the quality of the sound when playing I just wondered if this was normal, it quiet otherwise, thanks Gary.

    Can you be more specific, and include ALL the gear being used, and how it's all connected?
