Description Michael Rath trombones are found in almost every conceivable musical situation: in symphony orchestras and opera houses, in film and television studios, in pop and commercial music groups as well as brass bands, wind bands, big bands, jazz and funk groups, and so many more genres and ensembles. The large bore R4 are available with an F valve section with the designation 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” R4, you can purchase just the F valve section to fit your instrument.
