Has anyone done a good a/b comparison of the rm 100 and rm50 thru the same cab? I Picked up an Rm50combo cheap and while I couldn't get along with the celestion g12 75 in it, it sounds amazing thru my 412 (2 eminence super v and 2 celestion g12 t80s) I'm beginning to think I like it more than my rm100 but I can't put my finger on it, anyone weigh in on this?
