new member here, so sorry if i am in the wrong section :-\
anyway, i have a marshall 30w DFX combo amp, and whenever i have it in overdrive, i heare this really loud buzzing, but then when i touch something metal on it, or the strings, it gets a little bit softer, but its still there. anyway to help this?
and for anyone who has a the same, or similar amp, does it make some sort of popping noise when you turn it off?
i just want to know if theese thigns are normal , or if there is some way to fix it. thanks
