Rath R4 Bb/F Trombone - Hagmann

ProZone Insight

The medium/large bore R3 trombone and the large bore R4 are available with an F valve section with the designation of R3F and R4F.

Michael Rath also offers the R4 and R4F models with "in slide" tuning,

Two valve choices are available, both Swiss designed: the René Hagmann valve or the Willson Rotax valve. The Hagmann is free flowing and well balanced between open and closed operation. The Rotax has a more traditional feel, offering a little more resistance, preferred by many players.

Because of the modular construction of Michael Rath custom trombones you can remove the valve section and replace it with a detachable gooseneck, available as an option, creating a straight tenor trombone. Similarly, if you already own a “straight” R3 or R4, you can purchase just the F valve section to fit your instrument.


8.5" yellow brass bell (a yellow brass bell will sound more brilliant and brighter than gold and red brass bells with a consistency of tone.)
Yellow brass tuning slide (Yellow brass and nickel silver tuning slides allow for clearer articulations than gold or red brass and can feel slightly more open.)
Bronze handslide (A bronze slide typically sounds darker and feels more centred. Bronze can be an excellent choice, for the R4 or R9 models, for a player searching for a dark, symphonic sound.)
Hagmann rotor (The Hagmann is designed to cause as little disruption to the airflow as possible and feels very open in the valve register, even through the pedal register.)
