Royer's R-10 “Hot Rod” 25th Anniversary limited-edition ribbon mic is their most popular model. The R-10 Hot Rod is fitted with a custom 25th Anniversary Edition transformer that gives this microphone 5dB more output than standard, with a punchier feel, increased low-midrange focus and more open highs. The R-10 Hot Rod also sports a 25th Anniversary black-accented trim package that looks as cool as this mic sounds.
