Rogers is probably most famous for its "Dyna-Sonic" snare drum, which featured a number of innovations. In particular was a unique cradle in which the snare wires were supported. This meant that the longitudinal tension of the snare wires could be adjusted independently of the vertical force holding the snares against the bottom head. As a result, the snares could be tensioned as tightly as the drummer wanted without having to pull the snares against the head so hard they constrained (choked) the head's vibration. This and other innovations (for example, a remarkably shallow -- 4/1000" -- snare bed) made possible by the novel tensioning arrangement gave the drum a relatively crisp and recognizably-clear sound. Dyna-Sonics were made from about 1961 until the mid-80's.
