Lonestar head hum issues

Post by Ehsaan » Tue Jul 31, 2018 2:39 am

Hi all
I have a Lonestar head which was bought in 2015 . The other day while using it I heard like a low hum which was on the clean channel . This hum increases when I raise the master volume . The techs here in India feel its an internal ground loop problem . Surprisingly this has happened with every Mesa I have owned . I love the amps but this issue is a bit of a problem . I own a Fender and a Suhr Hedgehog and these amps are chugging away with no problems . Can anyone advise me on this as to what I should do . The earthing in my apartment is fine ( I moved the amp to the studio and there was the same issue )
Thanks so much
Regards
Ehsaan
