Tony Dixon’s brass range of whistles feature thick-walled brass bodies, polymer headjoints and brass tuning slides. The thick-walled brass body adds a touch of brightness and solidness to the tone when compared to Tony’s all polymer models. Please be advised that as the brass body is thick-walled, it is not a light whistle (see specs below). If you are looking for a lighter whistle, you might try Tony’s “Trad” model in brass that has a thin-walled body and is much lighter. The type of polymer used for the headjoint is a plastic material that enjoys similar tonal characteristics to wood but doesn’t require the constant care and maintenance.
