i am not 100% convinced the trem on my brown super is up to snuff. seems weak to me. you have to have the intensity well above 5 to hear the vibrato easily and then really on the lower registers. now i understand this is a real pitch bending but i dont have a thing to compare it to. there is a brown concert on youtube with a much stronger vib but its a different cicuit i think. what do you think? a tube swap?? the amp was gone over completely a year ago and is not played much.
