Through a slow forming of the brass and directed use of historical production techniques, the Historic trombones have sound and response qualities very similar to those of original instruments. This is the reason that Historic and Standard instruments sound differently despite having the same dimensions, and despite the Standard instruments also being made partly using historical production techniques

STANDARD

HISTORIC
