Marshall DSL401 Combo OD channel issue

I have a DSL401 combo which sounds great on clean channel but both OD channels give a loud nasty buzz drowning out the guitar signal. This only exists with an input signal and is not there when signal is put in the fx return so must be something in pre amp section any ideas?


Before you assume the amp has a problem, Try another guitar and another guitar lead just to rule out the obvious stuff.


If you crank up the volume on the clean channel, is there a similar sound?
