Warm Audio's RingerBringer is a new all-analogue effect pedal that bares more than a slight resemblance to Moog's much loved – and sadly now discontinued – MF-102 ring modulator pedal. Beloved by guitarists from bands like Radiohead and Mars Volta, these ring mod effects also sound great on synths. In this video, we test Warm Audio's version on some of our favourite desktop instruments.
