Orange AD200 'popping'

Morning guys,

Just a quick one here. I have a Orange AD200 bought new last December. Its used heavily and pushed hard, but its always left to warm up properly etc. When hitting the low E (especially when dropped to D or C sharp) it makes an intermittent popping noise as you strike the string? All other strings seem ok - just the low end that seems to be an issue.

The sound is exactly like when a string touches a pick up magnet (but its not this). Does anyone have any idea? I am running it with two Orange Cabs - a 410 and a 115.

I am going on tour in May and I really don't want it letting me down :-/

Any advice is much appreciated! [/size][/color]
