Rath R4F Tenor Trombone

The large bore R4 is available with an F valve section and is designated as R4F. Michael Rath also offers the R4 and R4F models with “in slide” tuning. There are three valve options available for Michael Rath Custom trombones: the René Hagmann valve, the Willson Rotax valve and the Voigt valve. 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.
