I just got my 6m worked up a few days ago. the tech did a phenomenal job giving my horn an overhaul. he redpadded it him saxgourmet roo pas with noyek resonators. he said that it would make my 6m at its full potential and make the sound very dark. I looked up some info talking about how it gives it a bright tone and how it depends on the size of them. Can anyone give me some info on this?
